What is IRINN?
IRINN (Indian Registry for Internet Names and Numbers) is a division of NIXI (National Internet Exchange of India) that allocates and registers Internet Protocol addresses, including IPv4 and IPv6, and Autonomous System Numbers (ASNs) for its affiliates.
IRINN functions as the National Internet Registry (NIR) for India, providing a transparent, community-driven platform for coordinating Internet number resources within the country under established policies.
Organisations seeking direct resource delegations (such as ISPs, Data Centres, and Enterprises) apply for IRINN affiliation to establish authoritative custody of IP blocks and ASNs for public and private routing.
CORE FUNCTIONS OF IRINN
IRINN Resource Ecosystem
The operational journey from organisational affiliation to global Internet routing.
Organisation Setup
Applicant evaluates IP requirement and business structure.
IRINN Affiliation
Submitting affiliation application to establish official NIR membership.
Resource Request
Applying for IPv4 (/24-/23), IPv6, and ASN with network justification.
Policy Evaluation
IRINN evaluates application based on current active resource policies.
Resource Delegation
Approved IP subnets and ASNs are delegated for live BGP routing.
IPv4 Allocation Framework
IPv4 is an Internet Protocol address resource used to identify and route traffic across IP networks. Due to global exhaustion, delegations from IRINN are policy-governed:
Note on Usage: Address space is allocated/assigned for documented, specific purposes according to applicable policy and cannot be redistributed or sub-assigned beyond authorized conditions.
IPv6 Allocation & Assignment
IPv6 provides a significantly larger, 128-bit address space designed for modern scalable Internet infrastructure, 5G, and enterprise networking:
Hierarchy: IPv6 /32 → Subnetting → /48 Subnets → Enterprise Organisation Networks → End Sites/Users.
Autonomous System Number — ASN
An ASN uniquely identifies an autonomous system participating in global Internet routing. IRINN considers an organisation eligible for ASN assignment if it:
*From 1 January 2025, the first two ASNs are free as per referenced policy guidance; additional ASNs are subject to applicable fees. Verify current IRINN policy before publication.

Allocation vs Assignment
Understanding the conceptual difference between address delegation types:
● ALLOCATION
The right granted to an LIR / affiliate to use address space for subsequent distribution, sub-delegation, or assignment to downstream customers and internal infrastructure according to applicable policy.
● ASSIGNMENT
The specific, documented delegation of address space designated exclusively for use within an organisation’s own network infrastructure (cannot be further sub-allocated).
Minimum Resource Delegations
| RESOURCE TYPE | MINIMUM / REFERENCE DELEGATION |
|---|---|
| IPv4 Minimum | /24 — 256 addresses |
| IPv4 Maximum | /23 from applicable pool (512 addresses) |
| IPv6 Allocation | /32 for LIR affiliates |
| IPv6 Assignment | /48 for direct affiliates |
| Autonomous System Number (ASN) | First two free; additional fees may apply |
Who Should Consider IRINN Registration?
ISP / Broadband Networks
Licensed Internet Service Providers establishing core routing PoPs, CGNAT subscriber pools, and multi-carrier transit links.
Data Centres & Hosting
Indian carrier-neutral data centres and cloud hosting providers requiring portable address space for dedicated server fleets.
Enterprise Networks
Corporates, financial institutions, and fintech networks operating multi-location leased lines with independent BGP routing policies.
Cloud / Network Infrastructure
SaaS and PaaS platforms requiring stable, portable IP ranges for API endpoints, CDN routing, and disaster-recovery sites.
Multi-Location Networks
Entities interconnecting distinct regional offices over MPLS/BGP with unique autonomous system traffic engineering needs.
Autonomous Systems (Peering)
Networks connecting to NIXI (National Internet Exchange of India) peering switches to exchange domestic traffic efficiently.
IRINN Affiliation & Resource Custody
Because IRINN operates as a not-for-profit affiliation-type organisation under NIXI, IPv4 and IPv6 resources are allocated strictly to approved affiliates. Resource custody is maintained on an ongoing basis subject to annual renewal and Whois compliance.

IRINN or APNIC — Which Resource Registry?
The appropriate route depends on the organisation's structure, network topology, and resource requirement:
| OPERATING ASPECT | IRINN (NATIONAL INTERNET REGISTRY) | APNIC (REGIONAL INTERNET REGISTRY) |
|---|---|---|
| Ecosystem & Scope | Indian Internet number resource ecosystem under NIXI | Regional Internet Registry serving 56 Asia Pacific economies |
| Billing & Taxes | Invoiced in Indian Rupees (INR) with standard GST | Invoiced directly in Australian Dollars (AUD) |
| Network Focus | Domestic Indian networks, ISPs, and enterprise PoPs | Multi-country PoPs, global carriers, and regional data centres |
| Resource Transfers | Governed under national IRINN transfer policies | Governed under APNIC inter-RIR and regional policies |
IRINN Application Process
Requirement Analysis
Identify IPv4, IPv6, and ASN requirements, network topology, and routing needs.
IRINN Affiliation
Complete and submit the official IRINN affiliation application with corporate KYC.
Documentation & Justification
