Dns Relay Static Settings - D-Link Xstack DES-3528 Series Reference Manual

xStack® DES-3528/DES-3552 Series Layer 2 Managed Stackable Fast Ethernet Switch Web UI Reference Guide
When a DNS server receives a query, it checks to see if the name is in its sub domain. If it is, the server translates
the name and appends the answer to the query, and sends it back to the client. If the DNS server cannot translate
the name, it determines what type of name resolution the client requested. A complete translation is called
recursive resolution and requires the server to contact other DNS servers until the name is resolved. Iterative
resolution specifies that if the DNS server cannot supply an answer, it returns the address of the next DNS server
the client should contact.
Each client must be able to contact at least one DNS server, and each DNS server must be able to contact at least
one root server.
The address of the machine that supplies domain name service is often supplied by a DHCP or BOOTP server, or
can be entered manually and configured into the operating system at startup.
