SOA
Each DNS zone must provide a Start Of Authority record which contains administrative
settings. Some of them can be configured here.
Start of authority servername
This option determines the hostname of the primary DNS for the selected zone. Usually
a DNS zone is mirrored by secondary name servers. The value you configured here
won't be changed on the mirrors, so it is possible to determine the primary name server
which is responsible for the entries of the zone.
Start of authority email
Here you have to specify the email address of the administrative contact for the selected
zone.
Incremented serial number
Every DNS zone must provide a strictly ascending serial number. With this number,
secondary DNS servers decide whether the entries of a zone file have been updated
and therefore a zone transfer is required. The serial number will be incremented
automatically by SX-GATE after each modification. Nevertheless you can influence the
serial number by specifying a value yourself.
If the local serial number is lower than on the mirrors it can cause
inconsistencies. Check the serials especially after restoring a
backup.
14.4.2.1-C
NS
Specify all authoritative primary and secondary name server for the selected zone. This
will add the respective NS records to the zone file. The server names can be specified
relative to the current zone (e.g. "ns") or as an absolute name. An absolute name ends
with a dot (e.g. "ns.example.com.").
14.4.2.1-D
MX
Specify all mail servers (mail exchanger) for the email domain which corresponds to
the selected zone. This will add the respective MX records to the zone file. The server
names can be specified relative to the current zone (e.g. mail) or as an absolute name.
An absolute name ends with a dot (e.g. mail.example.com.).
