Hi,
Last Tuesday I got a delay notice triggered by an email I sent to the list.
That's unimportant, but while looking at it I saw this header:
Received-SPF: none (Address does not pass the Sender Policy Framework)
SPF=HELO; sender=lists4.suse.de; remoteip=::ffff:195.135.221.135;
remotehost=lists4.suse.de; helo=lists4.suse.de; receiver=exa.billmerriam.com;
I noticed the ipv6 address, and I was curious to check who it was:
[EMAIL PROTECTED]:~> host "::ffff:195.135.221.135"
Host 7.8.d.d.7.8.3.c.f.f.f.f.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.0.ip6.arpa
not found: 3(NXDOMAIN)
Huh?
I then checked the ipv4 part:
[EMAIL PROTECTED]:~> host 195.135.221.135
135.221.135.195.in-addr.arpa domain name pointer lists4.suse.de.
Clearly the address does exist. Now, who/what is to blame about the ipv6
counterpart? Guesses:
- Linux's 'host' program is not yet ipv6 aware.
- Linux's 'named' daemon is not yet ipv6 aware, or not configured
properly
- Ditto dns servers worldwide, or at suse, not yet ipv6 aware or not
configured properly
- Human (ie, my) error.
