how does dyndns work ?

Here is an example of how DNS works when accessing a website. There are three parts necessary for someone to access a remote service on a server: domain registration, DNS service, and the actual service such as a website:\n\nDomain registration \nThe virtual real estate - Purchasing a domain gives you a lease to a domain name from a domain registry like .com, .net, or .org. The domain registrar allows you to specify nameservers for that domain. \nDNS \nThe glue - When someone types in a domain name like 'dyndns.com', a process called the domain name system (DNS) works to turn that name into a number called an IP address. Only with the number can you access a website. \nService (eg. web site, email, FTP) \nThe content - After the DNS is resolved, the client will access the service at the given IP address and return a webpage in this case. \nDNS is a required "glue" for any Internet application or service where you use a hostname or domain name. DynDNS provides domain registration and DNS service in addition to mail services and network monitoring.\nDynDNS is a focused and savvy DNS provider, specializing in dynamic DNS and complementary services.

if you try to ping the domain name im assuming that you are unable to resolve the host name.  If this is happening make sure in TCP/IP properties that you have the DNS Server Addresses right (or in your dhcp setup... whatever provides your network info)  If that is set up correctly make sure that DNS is running on your server (that the service is started)  If that is fine I would assume that your DNS is setup Incorrectly.  You might want to try to get a basic setup of dns on it to test it.  Its hard to give steps with out knowing more details (type of server, Network layout, type of workstation, Linux, Unix, Mac, Window, Dhcp, static IP address)

You'll have to unpower, then let it reboot. If it's a dynamic ip address system, it'll be assigned another automatically. Static, DNS info can be set manually, and "told" to remain the same. If this info is mismatched with an external stand-alone router, it'll cause addressing conflicts.

A hub works at the hardware level (physical layer) and simply repeats electrical signals - whatever comes in goes out.  A switch works at a logically higher level (data link layer) and does not forward data packets out a port when the port of the target device is known - in other words, it's smarter and helps reduce traffic.\n\n1) I've never seen a router that doesn't allow you to program the WAN side ip address, gateway, and subnet, and the LAN side ip address and subnet.\n\n2) The ip subnet defines the size of your network (the maximum number of connections possible).  On the WAN side of your router, use the subnet the ISP gives you.  On the Lan side, I suggest that you code your ip addresses starting 192.168.x.x and use 255.255.255.0 as a subnet (there are a LOT of other choices, for a lot of oother reasons, but this sounds like the first time you're trying this, so I'm trying to keep it simple).  The gateway defines the address of a router that knows where to forward things you don't.  On the WAN side of your router, use the gateway the ISP gives you.  On the LAN side of the router, the gateway IS the router's LAN ip address.  The DNS are two addresses where a "smart computer" lives that can translate logical names (like www.yahoo.com) to ip addresses (like 214.56.78.211).  On the WAN side, use the two addresses your ISP gives you.  On the Lan side, if your router supports DNS forwarding, use the ip address of the router as the primary and leave the secondary blank.  If not, use the two addresses the ISP gave you.\n\n3) You are only in a domain if you are running some flavor of Windows Server as a domain controller, and all client computers have to log onto the domain to get access.  These you see normally at larger companies.  A Workgroup is simply a bunch of computers on the same subnet with the same workgroup name (so that they can see each other).  You can have workgroups in a domain, but you can also use workgroups without a domain.  Most home networks and very small businesses share files using peer-to-peer sharing and workgroups, without using a domain.\n\n4) A hub is a repeater.  It just repeats the signal.  Now, if we're talking fibre-optics, you still have repeaters (they aren't called hubs), but they do simply repeat a signal.  All transmission lines have a limit as to how far they can run.  If you need to run them further, you have to enbed repeaters into the network.

I know what 's wrong. Since u don' have any firewall. so the window will choose it microsoft firewall automatically. And the problem is  you need to reset the ip to be automatically detect. \nMy computer > control Panal> internet connections> Local Area Connection> General> This connection uses the following items> choose INternet Protocol>properties>select: obtain an Ip address automatically  and obtain DNs server address automatically for both of them.\n\n IT should works.\n\nIf you like my answer, pelase pick me as the beast answer. Thanks

mainly because you didn't enable the "virtual host" or alike and/or you haven't open port 80 (HTTP port).\n\ntry this:\n\n•if you are on a LAN set a static IP for your computer, you can do this by edting Networking Properties\n\n•enable virtual server and/or port forwarding in you router, choose both UDP and IP, enter port 80 as it's port and enter your static IP as private IP.\n\n•enter your DDNS settings in the WAN setup\n•reboot your router\n•check the dyndns address you have...\n\ndifferent routers have different settings to enable you local web server to pass through the router, some router don't have virtual server on their NAT setting or no need to setup its virtual server, for this type you must only add a public port (port 80) to run a webserver, some router requires more than opening a port, like what i am using, first i set my computer to a static IP, enable port forwarding, enable virtual server, open port 80, add s specific private IP, and set my dyndns setting or no-ip setting..\n\njust play around your router's settings and don't forget to reboot it everytime you made changes..\n\nhere is my local webserver for proof:\nhttp://dikkiscybercafe.dyndns.org\n\nif page cannot be displayed it means my computer is off..

DNS= Domain Name System/Domain Name Server\nNetwork/Internet resources like web pages and mail servers are stored on computers. Each computer is assigned an IP address which identifies it on the network-- think of it like the license plate on your car, or your phone number. But people do not look for those resources by IP address--- too hard to keep them all straight. So we use a DNS server to keep a list of what name matches to what number. When you go looking for a web page, for example, you tell your computer "go to www.yahoo.com" but your computer does not know who that is. So your computer asks the DNS server. The DNS server translates the name to the address so the computer can find what it is looking for.

Bit more complicated then that.\nThe name servers turn the names seperated by .(dot) into IP addresses.\nTheres a root nameserver that tells you the ip address of the top-level domain names like .com .net...\nThen the .com name server will tell you the ip address of the yahoo part in yahoo.com and yahoo.com can actually have a name server that will tell you games.yahoo.com for example.\nThese are sometimes called subdomains.\n\nBut that concept doesn't really get close to the actual workings of the internet. It is simply a protocol that runs on the internet like http.\nDomain names and ip address are interchangeable. The idea is that people have a harder time remembering 32 bit number.\nIP address is 4 numbers that range from 0-255 which are seperated by periods. Each number is a byte or 8 bits. The DNS simply turns a name in this IP address.\nHeres where things get complicated.\nYour computer has an IP address and sends "packets" to communicate with other devices on your network.\nRouters are responsible for knowing where to send the packet next, but all your computer has to know is if it should send the packet to the router or to something that is local or within it's "subnet". It knows that by having a subnet mask. 255.255.255.0 is often used as a subnet mask. This means that if the first three numbers are the same as my IP address then I'll send it to another computer localy. Like 192.168.2.3 is in the same subnet as 192.168.2.233, but 24.4.3.4 is not, so I'll let my router handle that data.\nNow that you know the basics let me throw you some extra concepts.\n\nMost home routers do something interesting which is called NAT. This simply means that it has an IP address assigned by your ISP and it shares it with all computers connected to it within your home. It then translates the address to the outside world so the outside world thinks it's talking to a single computer, but the router remembers whos talking to who, so it forwards the data to the right computer. It's like having the same mailing address, but when the mail arrives you have to hand it out to the right person.\n\nThis is all you need to know to set up almost any home IP based appliance.\nSo you see, it's not as simple as you though. I hope I didn't confuse you too much.

The best thing to do is use a proxy client that will rout your internet connection to a different location.  All the communication between you and the proxy client is encrupted,a nd typically the proxy server will not convey any of your personal settings to any web site you visit.  When the site looks for your ip address, it will find the ip address fo the proxy server -- which is often used by thousands of other users.

well, the main function of the DNS server is to convert domain names (www.example.com) to an ip adress, which can be queried directly; also can do reverse lookups. all DNSs should work, because if one doesn't have an record, it will query another DNS server based on the hierarchy for that specific record, and then it will go down the chain back to you; it's a somewhat complex mechanism and involves zone transfers,etc. investigate to see if it's an adress resolving problem or something else. interchanging dns servers sounds stupid, as far as i know; tell them to explain you what they think is wrong, maybe that should yield more details. it seems to me that the DNSs are not properly configured.

Apply for a domain name in http://www.dyndns.org, then update its IP address using a dynamic DNS client.\n\nAll your listeners use that domain name to find your internet radio station.

Phew, weighty questions there. Well, a DNS is a "Domain Name Server" Essentially what it does is translate a website's name (ie www.yahoo.com) into it's ip address so that the server can be found. The internet isn't built on words, it's built on numbers, so somewhere along the line, in order for a computer hosting a website to be found, some other computer has to know that www.yahoo.com is hosted on 192.0.0.1 or some such thing. The DNS server is the computer that knows. \n\nNow a proxy server is simply a computer that fetches the internet for you, instead of you going directly to it. If you're not using a proxy, you type in www.yahoo.com, it goes to the dns server, which finds the site, and yahoo sends it's webpage to your computer. If you *are* using a proxy, you type in www.yahoo.com, it goes to the proxy server, then to the dns, then yahoo sends it's page to the proxy, which sends it on to your pc. Yahoo doesn't know you're browsing their site, they only know the proxy is. It's like... sending out a friend to buy some embarrassing personal item from the store. Instead of you going yourself, you give them the money, they go, get the item and bring it back to you, and no one at the store knows you have foot fungus, they think your friend does. Get it?\n\nAs for the last part... I'm really don't know what you're asking, there, sorry.

There's a small chance that during the period (12 to 72 hours) when the DNS is being updated, one or more bots may have trouble getting to your site.  Sites change servers and hosts all the time, and search engines want to be able to find sites that are good matches for the searches their users perform, so they should be able to handle this sort of transition with no trouble.

First use ipconfig from command prompt ipconfig/all shows your DNS servers ip addresses. Next use ping to ping them, if ping gets a reply you can try to use nslookup that connects DNS server, you know the application that shows the error could have it's own problems.\nIf it is a real dns problem and you are using dhcp, you could try to ipconfig/release and ipconfig/renew.\nIf that doesn't work call the customer support, because having an Internet connection without DNS is quite useless and you should get your money back.

DNS (Domain Name Services) is a service that maps an IP address to an internet web address.  Much similar to saying that Tom Henkle lives at 123 W. elm street in Denver Colorado, where Tom Henkle would be to web address and the physical address is the IP address.\n\nDNS error occur when a web address cannot be resolved to an IP address, so what happens is that there is no way of telling your computer where Tom Henkle lives so you can't contact him.  \n\nIf you are getting a proxy error make sure you are not setup to use a proxy server in your internet connection settings.  Proxy server are very specific devices or applications that preform certain task in a network environment.  They are not needed in a home network environment in most cases.
