So Kevin what your saying is someone using my dns created a record with
fe80::? I was under the impression that bind what trying to listen on that
subnet.

 

Thanks Paul

My guess would be that some miscreant out there created a glue AAAA record
with an RDATA of "fe80::" and your network stack balks at connecting to such
an abomination.

Hi, I have been using bind 9.9.4 for awhile suddenly looking at the looks I
see lots of socket.c errors. Looking at this it seems that bind is
complaining about the link local ipv6 address , I enabled ipv6 awhile back
and I just noticed this.

Aside from having my global ipv6 addresses here is the link local on that
box.

 

          inet6 addr: fe80::206:5bff:fe8e:XXXX/64 Scope:Link

 

 

Has anyone ran into this issue, I do have listen-on-v6 { any; }; and im
assuming if I was to just add the global ipv6 ips this would go away but I
guess im wondering does bind not listen bind itself to link local ip as well
? what is the recommended way to go about fixing this. 

 

 

BIND 9.9.4 (Extended Support Version) <id:8f9657aa> built with
'--enable-rrl'

 

 

Thanks, Paul
