ahcp-generate-address - perform IPv6 address generation
ahcp-generate-address
[ -p ] { -r | prefix } [ mac-48 ]
Ahcp-generate-address generates
IPv6 addresses from a given prefix and either a given MAC-48 address (an
Ethernet hadrware address) or a randomly drawn host number. It is usually
invoked by the ahcpd daemon, but may also be used directly.
- -p
- Generate
a prefix rather than a node address.
- -r
- Use a randomly generated RFC 4193
prefix.
- -s
- Use a randomly generated subnet number rather than 0. This is
only useful with -r, or when given a /48 prefix.
- prefix
- Use the given prefix.
/64 is implied, except when -s is specified, in which case /48 is implied.
- mac-48
- Generate a host number from the given MAC-48 address. If omitted,
the host number is drawn randomly (and the local/global bit is set to zero).
Generate a host number from a given prefix and MAC-48 address:
- $
ahcp-generate-address 2001:DB8:1234:5678:: 12:34:56:78:9a:bc
Generate a host
number from a given prefix and a randomly chosen host number:
- $ ahcp-generate-address
2001:DB8:1234:5678::
Generate a random /48 prefix according to RFC 4193:
- $ ahcp-generate-address -p -r
Generate a random /64 prefix according to RFC
4193:
- $ ahcp-generate-address -p -r -s
