Re: [gentoo-dev] ThisAddressDoesNotExist

[Mickey Mullin]

You should have your own IP address listed in your /etc/hosts file.  For DHCP
addresses, there's a post on forums.gentoo.org about it, but it appears to be
down again.  If I remember after forums comes back up, I'll send along the
appropriate text (along with a link to the post - it's from the thread related
to a "sticky" at the top of one of the forums).

Basically, your resolver is either ignoring /etc/hosts (if you DO have the entry
for your address there) or, failing to find your IP address in /etc/hosts it's
trying to resolve the mnemonic for that IP address (which is, of course,
impossible for 192.168.*.* addresses).

You can avoid the problem in the meantime by using the options that turn off
name resolution (often a "-n" switch - "route -n").

Also, "host <any martian address (192.168..., 10..., etc.)>" will generally fail
in some way or another.

One final possibility is that your ISP's name servers resolve all
martian/private addresses to "ThisAddressDoesNotExist" just for giggles.  ;)
