Ddclient not updating zoneedit

There may also be several secondary or slave servers that have copies of information from the primary, and act as backups in case the master server for the zone is unavailable.

A single DNS server may host multiple zones, or sometimes may not host any at all.

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.

DNS is a protocol used primarily for converting hostnames like IP addresses like, and vice-versa.

However, this does not have to be the case- a DNS server can be both a master for some zones and a slave for others.

There is no upper limit on the number of servers a zone can have, although few have more than three.

Every zone should have at least one secondary server in case the primary is down or un-contactable for some reason.The important and root domains have 13 servers, as they are critical to the functioning of the Internet and frequently accessed.Generally, the more slaves a domain has the better, as long as they can all be kept synchronized.The most common parent domains like .com, and au are managed by companies that charge for zones registered under them.This means that you cannot simply set up a DNS server that hosts a domain like and expect it to be visible to the rest of the Internet – you must also pay for it to be registered with one of the companies that adds sub-domains to the domain.
