Answer to Question #215069 in Computer Networks for ERIC

Question

IPv4’s ARP and IPv6’s Neighbor Solicitation both map an address from one space to

another. In this respect they are similar. However, there are several differences. In what

major ways do they differ?

Note any areas where you may want or need some further explanation. Ask questions of your

fellow classmates.

Answer 1

IPv6 uses NDP (Neighbor Discovery Protocol) to map to MAC address whereas uses Address Resolution Protocol. There are differences between IPv4's an IPv6's in terms of the type of address mapping used by both networks. The difference between the two is similar concerning address mapping, but there are some differences.

The IPv6 is a 128-Bit IP address while IPv4 is a 32-Bit IP address

In terms of headers field offering IPv4 offers 12 headers while IPv6 offers 8 headers.

The IPv6 binary bits are separated by a colon(:) while IPv4 binary bits are separated by a dot(.).

In terms of addressing method, IPv4 uses numeric while IPv6 uses an alphanumeric.

The IPv4 supports broadcast and have checksum fields whereas IPv6 lack checksum fields and doesn't support broadcast.

The place I may need more clarification is in the part of;

One is to explain how the newer ARP operates through request operation

The second area of concern is to ask how to cal calculate the payload size of an Ethernet frame carrying an Ipv4 or IPv6 packets.

Third, I would need more clarification and explanation on the differences between Address Resolution protocol and Reverse Address Resolution Protocol.

Fourth how to simplify IPv6 to the simplest form and the protocol being used.
