- To configure Domain Name System (DNS) for
clients with dynamically configured IP addresses that are provided
by a Dynamic Host Configuration Protocol (DHCP) server, you usually
configure the following at either the DHCP server or applicable
clients:
- DNS host name (or names) for the client
computer. For DHCP clients, this must be set at the client computer
or assigned during unattended setup.
- Primary and alternate DNS servers that the
client uses to assist in resolving DNS domain names. For DHCP
clients, this can be set on the DHCP server by assigning the DNS
server option (option 6) and providing a configured list of
ordered IP addresses for the DNS servers that the client is
configured to use.
- A list of DNS suffixes to be appended for use
in completing unqualified DNS names that are used for searching and
submitting DNS queries at the client for resolution. For DHCP
clients, this can be set on the DHCP server by assigning the DNS
domain name option (option 15) and providing a single DNS
suffix for the client to append and use in searches. To configure
additional DNS suffixes, configure TCP/IP manually for DNS
configuration.
- Connection-specific dynamic update and
registration behavior, such as whether specific network adapters
that are installed at the client dynamically register their
configured IP addresses with a DNS server. For DHCP clients, the
default is for client connections to register their configured IP
addresses with a DNS server. To modify this behavior at the client,
configure TCP/IP manually on the client for DNS configuration.
- DNS host name (or names) for the client
computer. For DHCP clients, this must be set at the client computer
or assigned during unattended setup.
For more information about how to configure other DNS for DHCP clients, see the applicable TCP/IP or DNS client documentation that is provided by the appropriate vendor.
By default, the DNS client does not attempt dynamic update of top-level domain (TLD) zones. Any zone that is named with a single-label name is considered to be a TLD zone, for example, com, edu, blank, my-company. To configure the DNS client to allow the dynamic update of TLD zones, you can use the Update Top Level Domain Zones policy setting or you can modify the registry.
