[d...@brandmauer ~]$ host www.bbc.co.uk 127.0.0.1 Using domain server: Name: 127.0.0.1 Address: 127.0.0.1#53 Aliases: www.bbc.co.uk is an alias for www.bbc.net.uk. www.bbc.net.uk has address 212.58.253.68 Host www.bbc.net.uk not found: 2(SERVFAIL) [d...@brandmauer ~]$ I did sniff connecction and It seems that the query that fails is a MX request of www.bbc.net.mx. Odd thing. When I ask to a exchange dns server, query is okay.
