Just had a hootin good time here....never seen a host like this before:


The below should alert on web access...not sure if I'll sig up DNS 

alert tcp $HOME_NET any -> $EXTERNAL_NET $HTTP_PORTS (msg:"POLICY 
International Domain Name web access"; flow:to_server,established; 
content:"Host|3a|"; content:"xn--"; http_header; within:100; 
classtype:trojan-activity; metadata:ruleset community; 
sid:10000052; rev:1;)

Maybe useful, maybe not.
