11 DNS Commands
A Domain Name System resolver is an internet service that translates host names into IP addresses. Every
time you use a host name, a DNS service must resolve the name to an IP address. You can configure up to
three domain name servers. If the primary DNS server does not know how to translate a particular host
name, it asks the secondary DNS server (if specified). If this fails, it asks the third DNS server (if speci-
fied), until the correct IP address is returned (resolved). If all DNS servers have been queried and the name
is still not resolved to an IP address, the DNS resolver will fail and issue an error message.
