the first group of four x's are the IP address itself; the four x's after the ip address are the port number.\n\n127.0.0.1:80 would be the localhost Web server default port;\n\n127.0.0.1:21 would be the localhost default FTP port;\n\netc.

DHCP: Dynamic Host Configuration Protocol. Suppose a computer belonging to a network and without a fixed IP address. When it is turned on, it requests network configurations (this request is sent as a broadcast request - everyone in the network can listen, but only a DHCP server will answer). The DHCP server answers this request with informations as IP address, netmask, gateway IP, DNS server, and so on. This IP address can be valid by a period of time (depends on the DHCP server configuration), and, when this period is over, another network configuration request is sent to the DHCP server.\n\n\nDNS: Domain name system. It is used to translate IP address in  readable (or sometimes not ;-) ) names. For example: when you type www.yahoo.com in address field of your browser, a request is sent to your DNS server (that can be fixed or got by DHCP request) and the server answer with the IP address of that name. With this address you can do all the communication needed. The inverse also can be done: you request the name of a host and the DNS answer the name of that host. Below is a link for BIND site, which is a very used DNS server. And a HOWTO too ;-)

Given an IP address A.B.C.D, the decimal form is:\nD + 256*C + 256*256*B + 256*256*256*A .

IP's are assigned to clients by a service known as DNS (Domain Name Service), your ISP has a DNS client that connects to the closest DNS on its route to query for a free (re-usable, of course!) IP. when it finds one, it assigns it to you, and registers that IP with the DNS (so it is not 're-assigned' while you are using it!).\nThere are only 7 DNS in the whole world, and they manage to keep up the traffic of the whole internet, pheew, think about that hardware, sweet God!!!\n\nMoreover, IP's refer to a 'domain name'. right, the numbers encrypt an actual name. like, www.yahoo.com = xxx.XXX.xx.XXX . Thus, if you want your computer to have always a same 'domain name', you need a "static IP", something you have to pay the DNS services a lot of money for...

A subnet mask is what determines what part of the IP address represents the "network" portion, and what part represents the "host" portion.  \n\nAn IP address is 32 bits, and the most common subnet mask you will probably see is 255.255.255.0.  If you write this out in binary, that's 24 '1' bits followed by 8 '0' bits.  The network interfaces take an IP address, like 192.168.1.123 and put it through a logical "OR" function with the subnet mask.  Any bit "ORed" with a 0 results in 0.  So the result of applying the 255.255.255.0 subnet mask with the 192.168.1.123 IP address results in 192.168.1.0.  So the network is 192.168.1.0 and the host on that network is 123.  \n\nThere is much more to IP addressing but this should give you enough to get started and do some searches.\n\nYou also asked about a gateway, the term "default gateway" is used to refer to the router that a host will use to communicate beyond the local network where it is attached.  If you have a home network with a Linksys or similar router for example, it might be 192.168.1.1 and this would be your default gateway address, the hosts go through that router to get to the Internet and everything else that is not locally connected.\n\nTo find your subnetmask, on a Windows PC you can bring up a command window (Start, Run, cmd) and give the command "ipconfig" and you will see your IP address, subnet mask, and default gateway.  You can also right-click My Network Places and select Properties, then click on the adapter and the info bar on the left will tell you the address and mask.  On a Unix platform, instead of "ipconfig", typically the "ifconfig" command is used.\n\nYou also asked about DNS1 and DNS2, these are the Domain Name Server addresses your machine talks to in order to "resolve" a name (like www.yahoo.com) to an IP address (like 216.109.118.77) for example.  Computers need to communicate using IP addresses, but we humans much prefer names, and DNS is what handles the conversions.  You can do lookups manually if you want to try it.  Brng up a command prompt and type "nslookup" to run the nameserver lookup program.  And the ">" prompt you can type names, like www.cnn.com, and it will answer you back with IP addresses for that name, give it a try.

Do you mean IP Address? And what do you mean by trace: Find somebody's location or IP Address?

Domain Name System\n\nIt converts a domain name, such as answers.yahoo.com into an IP address such as 9.44.120.7 which is used by the network to locate computers

I assume you mean the IP address of a dns server\n\nYou can do a reverse DNS Lookup at http://remote.12dt.com/rns/

in windows you can type `ipconfig` in the command prompt. in linux you can type `hostname -i` into a shell.\n\nor - from each of these machines you can visit www.whatismyip.com and it'll tell you.

sounds like you are using firefox.  try internet explorer if you still have it.  it means that your browser is trying to find it and it has taken too longto find it, so it has stopped.\n\nit happens to me all the time.  i refresh or go to internet explorer really fast.  or just give up..\n\nlater:\n\nooo!  and it could also mean that the link you gave or in this case ip number, isn't correct.  make sure it is correct!
