Ipv4 vs Ipv6

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 threats are different for the IPv6 than the IPv4.

One reason why IPv6 is considered safer is that it uses 128 bits for its address which is also in hexadecimal. Having a bigger address means it takes longer time to find the address and having it in hexadecimal makes it even tougher to figure out. IPv6 also supports IPSec, which supports better security while sending data across the TCP/IP Network. IPv6 is considered safer because of the IPSec where in IPv4, there are many compatibility issues and without having the IPSec enabled, it can be a security fault. IPv6 includes security-orientated functionality by default whereas the IPv4 does not. Now some people might differ that the IPv6 is not more secure than IPv4 because of the poor allocation of the IPv6, the main issue with the security of the IPv4 was the address size being so small, but the IPv6 does have a larger address, it still has the potential to have problems, even though it may take a few thousand errors to conduct the error.

The address size of the IPv4 is to be 32 bits where it is in a regular format of an IP, example 192.168.23.157 whereas the IPv6 has a large hexadecimal format which looks like, 21DA:00D3:0000:2F3B:02AA:00FF:FE28:9C5A. The larger address size is considered to make the IPv6 more secure but as stated before, there can be issues that can make the longer address a problem. The reason why the address is longer in v6 is because it can support over...
