4.1.5 System IPv6

IPv6 (Internet Protocol version 6), also called IPng (IP next generation), was developed by the
IETF (Internet Engineering Task Force) as the successor to IPv4 (Internet Protocol version 4).
Compared with IPv4, IPv6 increases the IP address size from 32 bits to 128 bits; this solves the
IPv4 address exhaustion problem.
IPv6 features

IPv6 has the following features:
1. Adequate address space: The source and destination IPv6 addresses are both 128 bits (16
bytes) long. IPv6 can provide 3.4 x 10
hierarchical address division as well as allocation of public and private addresses.
2. Header format simplification: IPv6 cuts down some IPv4 header fields or move them to IPv6
extension headers to reduce the load of basic IPv6 headers, thus making IPv6 packet handling
simple and improving the forwarding efficiency. Although the IPv6 address size is four times
that of IPv4 addresses, the size of basic IPv6 headers is 40 bytes and is only twice that of IPv4
headers (excluding the Options field).
