[gentoo-user] Strange gentoo.org address

[Peter Humphrey]

Hello list,

Why do boxes on my network return this?

$ nslookup www.gentoo.org
Server:         127.0.0.1
Address:        127.0.0.1#53

Non-authoritative answer:
www.gentoo.org  canonical name = www-bytemark.gentoo.org.
Name:   www-bytemark.gentoo.org
Address: 89.16.167.134

(This is on the dnsmasq box, which has no difficulty with any other addresses.)

It doesn't cause Firefox a problem on my KDE workstation, but on this box and 
others the links text-only browser can't find the site. Not helpful when I'm 
trying to find a cure for a problem while working in text mode.

Short answer: it is correct, working as designed.

Long answer:

That answer came from a DNS cache, which by definition is not authoritative - 
it is merely a copy (which you trust to be legit)

It does match the actual records on the real auth servers:

So why can't links find the site?

Because I had a bad alias lurking in the undergrowth.

Sorry about the noise.
