Initial Comment:
Anonymous message posted by kuniga at users.sourceforge.net

I used bash-completion and ssh on IPv6 environment, then I
expected a completion as follows.

$ ssh fd00:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:5555

But actually I got a completion as follows.

$ ssh fd00:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx

When last 16 bits of IPv6 address contains only digits, this
problem occurs.

I tried to make a patch of this problem.

Message:
Thanks for the report and the patch. However the patch would AFAIK break [host]:port completions where "host" is a hostname, not an IPv4 address.

Alternative fix in git:
