Host ( A ) Resource Record
Host (A) resource records are used to map hosts names with their IP addresses.
A Host A resource record can be added to a dns zone in several ways:
One way is to use the DNS Manager to manually create a host (A) resource record for a static IP address assigned client machines.
Second is client machines can use DHCP Client service to dynamically register and update their own host (A) resource records in DNS Zone when an IP configuration change occurs.
Third is Dynamic Host Configuration Protocol (DHCP) enabled client computers running earlier versions of Microsoft operating systems can have their host (A) resource records registered and updated by proxy if they obtain their IP lease from a qualified DHCP server. (Only the Windows 2000, Windows Server 2003, and Windows Server 2008 DHCP Server service support this feature.)
Not all computers require the host (A) resource records, but computers that share resources on a network need them. Any computer that shares resources and must be identified by its DNS domain name must use host (A) resource records to provide DNS name resolution to the IP address for the computer.
Most host (A) resource records that are required in a zone can include other workstations or servers that share resources, other DNS servers, mail servers, and Web servers. These resource records make up the majority of resource records in a zone database.
The following illustrates creating New Host A Record in windows 2003
1. run the command dnsmgmt.msc to open DNS Manager
2. In the console tree, expand the DNS node "DNSServer" and browse to the primary forward zone mydns.
3. Enter host machine name and it's corresponding ip address in new host record dialog box
4. See success dialog comes up.
