Summary
Mojo Networks
research legacy
MOJO is a small network registered to Mojo Networks in Catharpin, Virginia. Despite the name it is not the Wi-Fi vendor once called Mojo Networks (the former AirTight Networks); this is an independent, long-standing network run around amateur-radio and hobbyist infrastructure.
What it's used for
- Hosting and routing for amateur-radio digital services — its announcements include several blocks out of
44.0.0.0/8, the AMPRNet space reserved for licensed amateur radio operators, associated with D-STAR, APRS and EchoLink systems. - A small amount of general hosting and consulting connectivity alongside it.
Notable
- The network is tiny and single-homed to a transit provider, yet peers widely — the profile of a technically active operator rather than a commercial ISP.
- Announcing scattered AMPRNet
/24s is a distinctive signature:44/8is one of the few legacy/8s set aside for a hobbyist community rather than an institution.
Interesting
- The name is a trap for classifiers. A network called "Mojo Networks" with a 1996 AS registration is easily mistaken for the enterprise wireless company of the same name, which is an entirely different and much later organisation.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 448 networks and 1,849 prefixes, as published 2026-10-29. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
