Our grantees at @TeachersInSpace are hosting an Introduction to CubeSat Flight Experiments on January 24-25, 2026 in Albuquerque, NM. The event is open to NM K-12 & informal educators, librarians, teaching assistants, and aides. Visit tis.org/in-person-2 to learn more.

In the mid-1980’s, Phil Karn KA9Q implemented TCP/IP for amateur packet radio on IBM PC’s, helping unlock IP over RF for hams long before the Internet was widely available. #44Net #44yearsof44net #hamradio #amateurradio #digitalinnovation

Over the Holidays, ARDC Board Member Harald Welte gave a talk at the 39th Chaos Communication Congress. You can watch the talk here: media.ccc.de/v/39c3-isdn-po… #ardc #chaoscommunity #opensource #digitalcommunications

The first SPARKI workshop of 2026 is later this month, in the shadow of the Artemis rocket at KSC. Learn more about the SPARKI program at ariss.org/space-pioneers… and thanks to @ARDC_73 for the support!

In September 1981, Hank Magnuski KA6M contacted Jon Postel and acquired the 44.0.0.0/8 block of ~16M IPv4 addresses for #amateurradio experimentation. #44net #44yearsof44net #digitalcommunications

44Net has remained active for more than four decades, continuing to support amateur radio experimentation with IP networking. #44net #44yearsof44net #amateurradio #digitalinnovation

ARDC will be closed for the holidays starting tomorrow, 12/20/2025, and we'll return to the office on Monday, 1/5/2026. Have a great holiday season, and we'll see you in 2026! #ardc #amateurradio 📸 Heather Katsoulis, licensed under CC BY-SA 2.0.

On December 10, 2025, 45 years after Hank KA6M put up the first digipeater in the U.S., ARDC debuted 44Net Connect, an easy-to-use service helping hams get started with 44Net. #ardc #44net #44yearsof44net #44netconnect

@supersat BGP docs are in progress pending further testing. If you haven't already, I encourage you to check out our new subgroup to connect with others using 44Net Connect: ardc.groups.io/g/44Net-connect.

@ARDC_73 How does BGP work with this? It looks like it's supported but not documented. I have a /29 and an ASN from 44net Connect. I assume I announce this over the wireguard tunnel (which has a separate, single address). But what IP/ASN do I announce to?

Big news for hams and experimenters: 44Net Connect is live! 🎉 A simple, modern way to start using 44Net IP’s, with no complex setup required. Works with a wide range of devices that support WireGuard. Check out the related blog post to learn more: ardc.net/introducing-44…

It's always a good time to be thankful, and we would like to thank our ARISS-USA sponsors including: @NASA SCaN @ISS_CASIS @ARDC_73 @AMSAT & @arrl

HAMNET is one of the longest-running and largest amateur radio community networks– spanning Germany and neighboring countries. Entirely volunteer built and self-organized, it’s a standout example of a self-governing, community-driven network: hamnet.eu. #hamnet

🎉 Today, we celebrate 45 years since Hank Magnuski KA6M put up the first digipeater in the U.S.: a significant milestone for packet radio! 🎉 #packetradio #digitalinnovation #digitalcommunications #amateurradio

Happy International Volunteer Day! 🎉 We'd like to give a huge thank you to all of our wonderful volunteers. Your commitment strengthens the AR and DC communities and helps ARDC make a global impact. We couldn't do this work without you! #internationalvolunteerday #ardcvolunteers

Hank Magnuski KA6M was among the first hams to send a packet through a satellite, experimenting with AO-10 after its 1983 launch. #hamradio #packetradio #44net #44yearsof44net

44Net was one of the earliest large-scale IP networks outside of ARPANET, connecting hams with TCP/IP over radio before the Internet was mainstream. #44Net #Networking #amateurradio #digitalcommunications #digitalinnovation
