How to set rDNS in Windows Name Servers
This article will guide you on how to set #rDNS records in Windows Name servers. rDNS means mapping the address to a #hostname.
Nslookup is an MS-DOS utility that enables a user to look up the IP address of a domain or host on a network. The #nslookup command can also perform a reverse lookup using an IP address to find the domain or host associated with that IP address.
PTR record ( a pointer record ) is the certain type of DNS record that resolves an IP address to a host name. Getting reverse #DNS going is done by finding the PTR records in use by a DNS server. These PTR records will be managed by the company that is in control of the IP address which was assigned to you.
1. A pointer (PTR) record is a type of Domain Name System (DNS) record that resolves an IP address to a domain or host name, unlike an A record which points a domain name to an IP address.
2. PTR records are used for the reverse DNS lookup. Using the IP address, you can get the associated domain or host name.
3. An A record should exist for every PTR record.
4. The usage of a reverse DNS setup for a mail server is a good solution.
5. While in the domain DNS zone the hostname is pointed to an IP address, using the reverse zone allows to point an IP address to a hostname.
