Amateur Radio Digital Communications

What Amateur Radio Digital Communications does

Amateur Radio Digital Communications (ARDC) is a California non-profit public benefit corporation, founded in 2011 and headquartered in San Diego, that operates 44Net—a globally routable IPv4 address space (44.0.0.0/8) comprising more than 12 million addresses reserved for licensed amateur radio operators. The address block traces its origins to mid-1980s packet radio allocations and is maintained today as a community service for non-commercial experimentation, learning, and infrastructure projects run by licensed amateur radio operators, radio clubs, and volunteer-run networks worldwide.

ARDC's product surface centers on three provisioning methods for accessing the address space: 44Net Connect (a WireGuard-based VPN service supporting single-device tunnels and routed subnets), IPIP Mesh (a community-operated overlay network using IP-in-IP tunnels, descended from the original AMPRNet), and BGP-announced subnets for advanced users with their own ASNs. Supporting products include a self-service Portal (portal.ampr.org) for license verification and IP allocation requests, AMPR.ORG domain registration, DNS services, and a UniFi Network integration for SMB gateway deployment. Notable use cases span remote station operation, BYOIP cloud services, club networks, linked repeaters, multi-site resilient backbones, and emergency communications networks (e.g., AREDN, HamNET).

The business model is non-commercial: 44Net access is free to verified licensed operators, with no fees charged for allocations, tunnels, or DNS. ARDC is funded by grants and donations—most visibly a $420,000 grant dated March 2023—and supported by a small professional staff (1-10 employees), volunteer regional coordinators, and a Technical Advisory Committee under board oversight. Go-to-market is entirely community-led through groups.io mailing lists, a comprehensive wiki (wiki.ampr.org), and partnerships such as the ARISS (Amateur Radio on the International Space Station) educational outreach program; there are no paid marketing channels, sales motions, or enterprise contracts. Recent strategic activity has focused on modernizing onboarding via 44Net Connect, expanding into the UniFi ecosystem, and pursuing a regulatory path to an IPv6 allocation (proposed 44::/16 block).

Core offering

ARDC administers the 44Net (AMPRNet) globally routable IPv4 address space (44.0.0.0/8), comprising over 12 million addresses, and provides it free of charge to licensed amateur radio operators for non-commercial experimentation, learning, and networking. Operators connect to the network through three provisioning methods — 44Net Connect (WireGuard-based VPN tunnels), IPIP Mesh (IP-in-IP overlay), and BGP-announced subnets — and manage their allocations through a self-service Portal after amateur radio license verification.

Product overview

Amateur Radio Digital Communications (ARDC) operates 44Net, a platform for licensed amateur radio operators comprising multiple interconnected products: the core 44Net address space (44.0.0.0/8 with over 12 million routable IP addresses), 44Net Connect (WireGuard-based VPN service for tunnel access), IPIP Mesh (overlay network using IP-in-IP tunnels), and the Portal (web-based management system for license verification and resource allocation). Additional offerings include AMPR.ORG domain registration, BGP-announced subnet routing for advanced users, and DNS services. These products enable non-commercial experimentation, remote station operation, and networking for the amateur radio community worldwide.

Broad incumbents

• Infoblox: Leading commercial provider of DDI (DNS, DHCP, IPAM) and network management for enterprises. Comparable as a managed IP-address-and-DNS stewardship platform, though Infoblox serves enterprise paying customers rather than a non-commercial amateur radio community.
• BlueCat Networks: Enterprise IPAM, DNS, and DHCP platform provider. Overlaps with ARDC's core function of allocating and managing routable address space and DNS records, but operates as a paid enterprise software vendor.
• EfficientIP: DDI-focused vendor providing IPAM, DNS, and DHCP management to enterprises and telecom carriers. Comparable to ARDC in managing address allocations and DNS at scale, though commercial and global rather than amateur-radio-only.
• Cloudflare: Operates one of the world's largest anycast DNS networks (1.1.1.1) and a broad edge/cloud platform. Comparable to ARDC on the DNS dimension (ARDC explicitly supports Cloudflare's 1.1.1.1 as a resolver option for operators), though Cloudflare is a much broader commercial provider.
• Cisco (Network Services / DNA): Major networking vendor whose portfolio includes IP address management, DNS, BGP route management, and network services. Comparable in the BGP-announced subnet and network-management dimensions of ARDC's offering, though vastly broader in scope.

Direct peers

• NS1 (IBM / itsdns successor): Managed authoritative DNS and traffic steering platform. Comparable to ARDC's DNS service offering for amateur radio operators, though NS1 targets commercial enterprises with global anycast routing and paid SLAs.
• AREDN (Amateur Radio Emergency Data Network): Community-built mesh network for licensed amateur radio operators focused on emergency communications. Listed as an autonomous network example built on 44Net and uses the 44Net address space, making it a directly comparable peer in the amateur IP networking ecosystem.
• IRLP (Internet Radio Linking Project): Community-operated VoIP linking system connecting amateur radio repeaters worldwide via the Internet. Listed on 44Net's wiki as a shared infrastructure example using the 44Net address space, making it a directly comparable amateur networking peer.

Regional players

• HamNET (DARC Distrikt C): German amateur radio broadband IP network operated under DARC, using 44Net address space for linked repeaters and IP services. Regionally focused on Germany but functionally similar to ARDC's 44Net in providing routable IP infrastructure to amateurs.

Others

• RIPE NCC / ARIN (Regional Internet Registries): Regional Internet Registries that allocate and steward IP address space globally, including the historical allocation of 44.0.0.0/8 to amateur radio. Comparable as stewards of IP address resources, though RIRs serve all address users rather than a single regulated community.
