TCP/IPv6 Configuration

The IPv6 standard differs from the IPv4 standard in many ways. The TCP/IP configuration for IPv4 and IPv6 on
NonStop servers is different in several aspects as well, see documents and links listed in section
But from NonStop SSH and comForte SecurSH/SecurFTP product's standpoint the differences are mainly related to the
new address formats of IPv6, new defines and different modes the NonStop TCP/IP processes with IPv6 support can run
in.

IPv6 Address Formats

IPv4 uses 32 bits for an Internet Protocol address, and can therefore support 2
128-bit addresses, i.e. the new address space supports 2
Although IPv4 addresses may be presented in various hexadecimal, octal, or binary representations, they are canonically
represented in dotted decimal notation, which consists of four decimal numbers, each ranging from 0 to 255, separated
by dots, e.g., 172.1.2.3. Each decimal number represents 8 bits (one octet) of the IPv4 address.

32
(4,294,967,296) addresses. IPv6 uses

(3.4x10 ) addresses.
