Ipv4 vs Ipv6

The IPv4 came before the IPv6 and these datagrams are similar in many ways but also differ in more ways than one. IPv6 came out in the year 2004 and still uses many of the features that made IPv4 so successful. IPv6 is supposed to become the new standard over the older version of IPv6, but it is tough for v6 to take its spot when v6 cannot support everything v4 does, basically v6 cannot connect to a v4 system. Some differences are that it is stated that the IPv6 is more secure than the IPv4, the address size went from 32 bits in the IPv4 to 128 bits in the IPv6, extensible protocols are more flexible in the IPv6, IPv4 and IPv6 are not compatible, the IPv4 will not be able to support additional nodes or support for applications, and the …show more content…
The reason why the address is longer in v6 is because it can support over 340 undecillion IP addresses. Mainly because the IPv6 has potential to have problems just like the IPv4 address problems. Also, the IPv6 has been broken down into geographical locations, meaning that the address can be tracked to a specific location in the world. The downfall in this part, in my opinion, in a hacker’s point of view, is that you can breakdown a specific location where you would want to attack, if you know the geographic location of the hexadecimal in the address. What I mean is that you can know the country code in the IPv6 address and focus your attack in that specific location. Having a random order of the v6 address would make it more reliable and more secure but also would allow disorder, not knowing where specific address might be located.
IPv6 is more flexible in using protocols which, are mainly defined as the Request for Comment (RFC) that we discussed in the discussions. Protocols are defined in the RFC, but the name of the protocol will be something like Internet Protocol, Internet Control Message Protocol, Telnet Protocol, and many more. The reason why these Protocols are more flexible in the IPv6 is for one, the IPv6 is a newer technology than the IPv4, and the IPv6 also has more functionality and allows more flexibility in the protocols, whereas the
