Then I have a new proposal which might not be so clean but
I think it is somewhat practical.
-Only think about inet and inet6. Forget about other protocol
family and sockaddr.
(Just as current jail only think about inet.)
-Just add an in6_addr structure(IPv6 address) member
"ip6_number" into the jail structure.
-Jail(2) specify "ip_number" and/or "ip6_number" into the kernel.
-Kernel treat "ip6_number" as just a same kind of extension
for IPv6 as "ip_number" for IPv4.
-Jail(8) command can also accept DNS name, and then it resolve
the name internally and,
if A record is obtained, specify its address into "ip_number".
if AAAA record is obtained, also specify its address into "ip6_number".
