how ipv6 is better than ipv4?

How is IPv6 different/better than IPv4? Expanding the pool of IP addresses (putting it mildly) yields other benefits as well. Because of the dearth of IPv4 addresses, much of the Internet relies on NAT (Network Address Translation). With IPv6, every device can literally have its own unique public IP address.

IPsec makes IPv6 more secure than IPv4 Internet Protocol Security (IPsec) was designed to provide network layer security (authentication and encryption). It was included as a mandatory feature in the IPv6 standards. ... These are terminated at the edge of networks. IPv4 IPsec is rarely used to secure end-to-end traffic.

IPv4 and IPv6 must coexist for some number of years, and their coexistence must be transparent to end users. If an IPv4-to-IPv6 transition is successful, end users should not even notice it. A dual-stack device is a device with network interfaces that can originate and understand both IPv4 and IPv6 packets.

Unlike RIP protocol that has only 15 hops at most, OSPF has no limitations in hop count. So OSPF converges faster than RIP, and has better load balancing. The drawbacks of OSPF, however, is that it doesn't scale when there are more routers added to the network.

CMIP is superior to SNMP because (as explained in the Advantages to CMIP link above) it can provide greater control over a network by a sysadmin. For instance, its security and notification services equal or surpass those available in SNMPv2.

Dynamic host configuration protocol (DHCP) still assigns dynamic addresses for IPv4 networks, but two newer protocols – SLAAC and DHCPv6 – are vying to do the job for IPv6. ... To complicate matters, a new DHCP – DHCPv6 – that performs the same function as SLAAC was independently created for IPv6.

IPV4, the traditional numbering scheme, uses four integers ranging from zero to 255 and set apart by periods. For example, "204.120. 0.15" is a valid IPV4 address. A newer IPV6 scheme, designed to eventually replace IPV4, uses a larger, more complex set of numbers mixed with other characters, such as letters.

Unless network infrastructure is running what is known as a “dual stack”, i.e. two independent networking stacks that allow the processing and subsequent translation of the two protocols, the infrastructure cannot easily handle both IPv4 and IPv6 at the same time.

KEY DIFFERENCE IPv4 is 32-Bit IP address whereas IPv6 is a 128-Bit IP address. IPv4 is a numeric addressing method whereas IPv6 is an alphanumeric addressing method. IPv4 binary bits are separated by a dot(.) ... IPv4 supports broadcast whereas IPv6 doesn't support broadcast.

The IPv6 address space is 128-bits (2128) in size, containing 340,282,366,920,938,463,463,374,607,431,768,211,456 IPv6 addresses. A bit is a digit in the binary numeral system, the basic unit for storing information.

IKEv2 is not as common as L2TP/IPSec as it is supported on many fewer platforms (although this situation is changing fast). It is, however, considered at least as good as, if not superior to, L2TP/IPsec in terms of security, performance (speed), stability and the ability to establish (and re-establish) a connection.

There are less than 4.2 billion available IPv4 IP addresses. In other words, there are more connected devices on the planet than there are unique, public IP addresses for them.

Parts of the IPv6 Address. An IPv6 address is 128 bits in length and consists of eight, 16-bit fields, with each field bounded by a colon. Each field must contain a hexadecimal number, in contrast to the dotted-decimal notation of IPv4 addresses. In the next figure, the x's represent hexadecimal numbers.

No, it is not necessary to create an AAAA record for your website as long as most traffic runs over IPv4, but I would argue that it probably is beneficial for the deployment of IPv6 to have more sites support the protocol.

No, IP and IPv4 are not same because IPv4(internet protocol version 4) is a part of IP(internet Protocol). Two versions of the Internet Protocol are in common use in the Internet today. ... An IP address in IPv4 is 32-bits in size, which limits the address space to 4294967296 (232) IP addresses.
