IN SOA format

[Peter Dambier]

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

Now you have the IPv4.

Originally the idea was to name the master dns-server or the
host you used to build the zone file on.

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 "hostmaster at schlund.de."

Some people know how to escape things to show an "@" in this string
but that breaks programmes.

Kind regards
Peter
