Hi Paul, make it as easy as possible. CNAMES might need another query and take time to resolve.
There is a tool "natnum" in the IASON tools at http://iason.site.voila.fr/ e.g.: $ natnum peter-dambier.de host_look("82.165.62.90","peter-dambier.de","1386561114"). host_name("82.165.62.90","gmxhome.de"). Here "gmxhome.de" would be a good name. You can do it by hand using dig ; <<>> DiG 9.4.3b2 <<>> -t a peter-dambier.de ;; global options: printcmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 43671 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUESTION SECTION: ;peter-dambier.de.

Many people and few programmes expect to see a dns-server for the zone here. Important is the email address e.q. peter-dambier.de. 9720 IN SOA ns15.schlund.de. \ hostmaster.schlund.de. 2.... Programmes expect "hostmaster.schlund.de." to mean "[EMAIL PROTECTED]" Some people know how to escape things to show an "@" in this string but that breaks programmes.
