I am having a problem with traffic bandwidth, and my syslog is full of the following type of issue: error (unexpected RCODE REFUSED) resolving 'target-express.com/AAAA/IN': 193.95.142.60#53 error (unexpected RCODE REFUSED) resolving 'target-express.com/A/IN': 2001:7c8:3:2::5#53 In today's syslog, there are 144258 instances of this, all related to http://serverfault.com/questions/672566/unexpected-rcode-refused-eating-up-log-files target-express.com. My questions are: is there anything I can do firewall-wise or bind config to stop this? Why would my bind setup be trying to resolve target-express.com (it's not my domain, nothing to do with me). I have checked my forwarders in named.conf, and none of them match the IPs showing in the logs (they are all basically different IPs, not just 193.95.142.60). My iptables reads: Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere REJECT all -- anywhere loopback/8 reject-with icmp-port-unreachable ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED ACCEPT tcp -- anywhere anywhere tcp dpt:http ACCEPT tcp -- anywhere anywhere tcp dpt:https ACCEPT tcp -- anywhere anywhere state NEW tcp dpt:ssh ACCEPT udp -- anywhere anywhere udp dpt:domain ACCEPT tcp -- anywhere anywhere tcp dpt:domain ACCEPT icmp -- anywhere anywhere icmp echo-request LOG all -- anywhere anywhere limit: avg 5/min burst 5 LOG level debug prefix "iptables denied: " REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain FORWARD (policy ACCEPT) target prot opt source destination REJECT all -- anywhere anywhere reject-with icmp-port-unreachable Chain OUTPUT (policy ACCEPT) target prot opt source destination ACCEPT all -- anywhere anywhere UPDATE: I've tried the following now in named.conf.options to block recursion. allow-transfer {"none";}; allow-recursion {"none";}; recursion no; Once I did this, I am now seeing the following in sys
