Real IPv4
for real hams.

Public IPv4 addresses for your projects.
Free to use for licensed radio amateurs.

44Net is a global block of IP addresses reserved for licensed amateur radio operators who want to learn, experiment, and create on the real, public Internet.

Get Started:

No NAT. Just ’Net.

44Net IP addresses are public, globally routable, and static — no NAT, no CGNAT. IP as it was meant to be.

44Net IP addresses are globally routable. Connected devices can have direct access to the public Internet.

By hams, for hams. Worldwide.

Across the street or around the world — When you access a resource on a 44Net IP, you know it's provided by a fellow ham in the spirit of amateur radio. Got a callsign? Get started.

How to Get Connected IPIP Mesh - Mesh overlay network

BGP - Announce a /24 subnet from your ISP or cloud provider - Bring your own ASN

VPN (limited beta!) - Wireguard tunnel to a 44Net point of presence over almost any network - No BGP or ASN needed - Home, mobile, or portable stations

Features

No NAT, just Net - 44Net IP addresses are real, globally-routable, public IPv4 addresses. No NAT, no port forwarding, no tricks.

By hams, for hams - When you access a resource on a 44Net IP, you know it's provided by a fellow ham in the spirit of amateur radio.

BYO Access - Use your own ISP, cloud provider, or home network. Build your network over copper, fiber, or RF. 44Net goes where you go.

What is 44Net? 44Net is a community-driven IPv4 network for amateur radio operators. It provides a platform for hams to connect, share resources, and experiment with networking technologies.

At the core is a block of IPv4 addresses free for licensed hams to use, available as individual IP addresses or subnets up to /24. Connect to the IPIP Mesg overlay network, or use BGP to announce your own /24 subnet from your ISP or cloud provider. Coming soon, a limited beta of a Wireguard VPN tunnel to a 44Net point of presence over almost any network, no BGP or ASN needed.

Why use it? Who is it for?

44Net provides a way for hams to get IPv4 address space and use it for the kinds of things hams are known for: experimentation, innovation, community, and more. Hams learn, experiment, and build on the airwaves — 44Net lets hams do the same with IP networking.

Why 44Net?

44Net is more than just IP addresses. It's also a community of hams who are passionate about networking and technology. By joining 44Net, you become part of a network of like-minded individuals who are eager to share knowledge, resources, and experiences.
