Advanced TCP/IP Settings â€“ The DNS Tab
Posted by admin on 11 September 2009 11:33 PM
The "DNS server addresses, in order of use box" at the top of the DNS tab is used to list the IP Addresses of the DNS Servers that will be used for name resolution. These servers are ordered and used in priority, so if one server does not work then it will move to the next one down the list. To set the order of IP Addresses, select an IP Address and press the up and down button on the right hand side.|
It is important to keep in mind that TCP/IP will not move on to the next server if it fails to resolve the request. It will only move to the next server if the first server it tries is unavailable (perhaps down for maintenance or in the middle of a reboot).
Append primary and connection specific DNS suffixes, and Append parent suffixes of the primary DNS suffix are enabled by default. These options are used for resolution of unqualified names.
The first option is used to resolve unqualified names using the parent domain. For example, if you had a computer name of â€œfrankâ€ and a parent domain called stinky.com it would resolve to frank.stinky.com. The query would fail if frank.stinky.com does not exist in the parent domain.
The second option is used to resolve unqualified names using the parent-child domain hierarchy. A DNS query will move one step up the domain hierarchy if it fails at the current level. It will do this until it reaches the root of the hierarchy.
The textbox on the right of the DNS suffix for this connection is used to explicitly set a DNS suffix that will override any other setting already specified for this connection.
Register this connectionâ€™s addresses in DNS will register all this connectionâ€™s IP Addresses in DNS under the computerâ€™s FQDN. Using this connectionâ€™s DNS suffix in DNS registration will register all IP Addresses for this connection in DNS under the parent domain.
