The DNS organises domain names and the associated Internet Protocol (IP) addresses into a searchable directory. Web browsers and applications refer to DNS servers in order to correlate domain names with their IP address.

The primary DNS nameserver is the DNS master and this holds the authoritative database of domain name/IP address pairings. The primary nameserver accepts any changes, additions or deletions to the domain name.

Secondary or tertiary nameservers are “slave” servers and store copies of the DNS database for use in case the primary nameserver is unavailable.

Scotland Online has considerable experience in handling the delegation of domain names, currently hosting over 10,000 domains.
