Hello,
today we discovered a hostname which is very slow to resolv with Unbound 1.4.21 as validating resolver. It works fine with all knid of other resolvers and oddly enough even with another Unbound instance. The host in question is esta.cbp.dhs.gov and resolve time after it is not in the cache range from around 2 to 5 seconds. I have take a tcpdump and can only see that the first answer come much faster but Unbound keeps asking for the same A record on different nameservers again and again.
Any idea what is going wrong? Thanks Andreas _______________________________________________ Unbound-users mailing list [email protected] http://unbound.nlnetlabs.nl/mailman/listinfo/unbound-users
