Try putting an entry for home-hehbbzsuy7 with the ip-address in /etc/hosts. 
Possibly also add the Fully Qualified Domain Name (fqdn) in there, something 
like 
192.168.1.5 home-hehbbzsuy7.snow.email.ne.jp home-hehbbzsuy7

Is the dns-server really reachable on/via 10.0.0.138 ? Try 'dig ns.nl.net' and 
see if it resolves to 193.78.240.1. Check the last four lines of the output 
of this command for te query-time and the server which was queried.
