I think that is what you are saying.
Yes, every nonexistent domain name is evaluated to <no such domain>.<my domain> which then resolves to my public IP (it is a wildcard dns record in action I think). That explains why domain name with trailing dot wasn't glued with my domain (two dots in FQDN are nonsense). I have no such behavior on Debian box without serach line explicitly set in /etc/resolve.conf. I also checked that on Windows boxes just to be sure it isn't DNS config related issue. I'm not suspecting wrong DNS configuration. I'm close to begin investigation of source code of libbind package because grepping over my file system didn't return anything related to configuration of resolver that might be useful.
