[as112-ops] discarding request from Colt IP 217.111.216.206

Hello all,

I guess that restarting the nameserver process fixed this issue.

Thanks a lot for your support.

Cheers,

If it is really ending up in CH then chances are good you will hit the node operated by SwissIX.

If you have a way to see the BGP next hop on the last COLT router you would be able to tell. Unfortunately the COLT LG is not very helpful in this case.

I have checked our AS112 node and did not see anything out of the normal, but restarted the nameserver process. Do your lookups work now?
