Ddclient not updating zoneedit

However, some domain authorities require it to be in a certain date-based format, such as YYYYMMDDnn.Normally a single server hosts either entirely master zones, or entirely slaves.

In fact, there is no way for other systems to know which server is the master and which are the slaves for a particular zone.However, by far its most common application is converting hostnames to IP addresses.Most systems use the DNS protocol to send requests to a server, which does most of the work of resolving a hostname into an IP address.Although there are several ways this can be done (such as reading the /etc/hosts file or querying an NIS server), DNS is the most common.As well as looking up IP addresses for hostnames, the DNS protocol can also be used to find the hostname associated with an IP address.A master server can also be configured to notify slaves when a zone changes so that they can perform a zone transfer immediately, ensuring that they are always up to date.

Every zone has a serial number, which is simply a counter that must be incremented each time any record in the zone is changed.Each zone contains multiple DNS records, each of which has a name, type and values.The most common type of record is the address or A record, which associates a hostname with an IP address.Slave servers can request a copy of all the records in a zone at once by doing a zone transfer.This is done a secondary DNS server when a zone is first added to it, and periodically when it detects that the zone has changed or the records in it have expired.source: On this page the DNS protocol and the BIND DNS server are explained, as is the Webmin module for creating and managing DNS domains.
