Bind with unresolved EDNS issues
I have considerable delay on address resolution.
I have opensuse 11.2 for my internal DNS server.
I get the error message " network unreachable resolving 'testats.inuvo.com/A/IN': 2001:500:2f::f#53 "
I have read a lot of Google searched sites that tell me I am not alone.
I have read that you should just disable the logging of the error - ?????? I want it fixed!
I have added the options=-4 to my /etc/sysconfig/named file - it must ignore that, I know it is the correct file since I can type " hello" , save and restart and it does not recognize hello as a command.
In the named file NAMED_ARGS is there. it does not show what it is used for directly but out of desperation, I put the -4 in it's quotes. I no longer see the network unreachable resolving in the log but I do see success resolving 'ccccc.com/A' (in '.'?) after disabling EDNS in the log so did it just disable the error being logged?
I added the option edns-udp-size 512; to humor things.
I did the tests to see if my firewall can handle EDNS packets, it passes.
I also ran from prompt: named -u named -c /etc/named.conf -4
It continues as before.
How can I disable EDNS permanently? ( at least till it is more of a used option )
I can see from Google searches this is a long time problem.
Let em also ask, network unreachable resolving , my NAT has no rules for IPV6, even if I did, the core switch from our ISP does not have an IPV6 gateway address nor does our ISP. Is it unreachable because of that? I wonder if I fully understand the error.
Still, it will resolve and work with IPV4 so why do I need IPV6?
