For a computer in Indiana University's ADS Domain, how can I register a DNS reverse lookup (PTR) record?
If you are using a computer that you have registered with Indiana University's Active Directory Services (ADS) Domain, you can configure it to use Dynamic DNS (DDNS). If a computer within the ADS Domain is configured to use DDNS, its forward lookup record will automatically be registered on the DDNS servers. The forward lookup record maps a hostname (fully qualified domain name) to an IP address. However, many applications also require a reverse lookup record, also known as a pointer or PTR record. A reverse lookup record maps an IP address to a fully qualified hostname.
The DDNS service associated with ADS does not automatically register
reverse lookup records. If you are using a static IP address (rather
than using DHCP), to register a DNS reverse lookup record,
send mail to the DNS administrator. For computers at IU Bloomington,
send mail to dns-admin@indiana.edu. At IUPUI, send
mail to dns-admin@iupui.edu . In your message, mention
the hostname and specify that your computer belongs to the ADS Domain.
