IP addresses and AS numbers are shared resources, available for use by anyone who needs them. Once you have received Internet resources from IRINN it is the affiliate organization's responsibility to ensure your Internet resources are managed according to IRINN address space management policies, including registration, usage responsibilities, and best practices.

Update your registration

The IRINN Whois Database is an official record that contains information regarding organizations that hold IP addresses and AS numbers in India.

Each organization that holds Internet resources is responsible for updating its own information in the database. As the database is used to assist with network troubleshooting and to help track network abuse, it is extremely important to ensure the contact details are accurate.

Public or private assignments

The affiliate can choose whether or not to designate their Internet resurces assignment or suballocation registration to be public or private:

- Public assignment: Others can view the affiliate's holdings on the IRINN or APNIC Whois Database
- Private assignment: Database record directs specific Whois enquiries to your organization, and the details are not available to the public.

Register route object

IRINN provides Routing Registration Services for all IRINN account holders. To use this service you will need to register a route object, which represents routing information, including IP address ranges and AS numbers in a compact form in the IRINNWhois Database.

According to the IRINN address space management policy, it is not mandatory for a affiliate to register a route object. However, from a network operation stand point, affiliate may be required to register a route object with IRINN. Some ISPs and network operators use route object information in the Internet Routing Registry database to:

  • Debug routing problems
  • Automatically configure backbone routers
  • Perform network planning

We suggest you discuss the requirement of registering route objects with your ISP.

Reverse DNS delegation

Forward translation

The Domain Name System (DNS) is a globally distributed Internet service. It is a hierarchical naming system where easy-to-remember names are translated into the numbers required for devices to network across the Internet.

Reverse translation

If you have a domain name and you want to find out the IP address that name belongs to, you can query the numerical hierarchy that co-exists with the name hierarchy: the reverse DNS. Reverse DNS delegations allow requesters to map to a domain name from an IP address. Reverse delegation is achieved by the use of pseudo-domain names in (IPv4) and (IPv6).
