About this network

A commercial wireless provider announcing a /18 of the amateur radio allocation, under a callsign's domain.

What it's used for

• A United States fixed wireless provider. 136,960 addresses across 115 IPv4 prefixes, twenty-two observed BGP neighbours, and no IPv6 announced.

Notable

• 44.15.64.0/18 is netname AMPRNET, registered to Amateur Radio Digital Communications.
• Addresses in it resolve as 44-15-95-255.mi6.w8cmn.net, whose second label is a callsign.
• Most other blocks are netname SAWL-1; one is FNW-MI2 registered to a different company.
• Three reverse domains appear, and two octet orders: 104.128.203.254.moline-mi.surfairwireless.net reads forwards, 254.27.164.184.surfinternet.com reads backwards.

Interesting

• The amateur radio address space was set aside for licensed operators long before commercial internet existed. Portions of it are now leased or used under agreement, and this is what that looks like in practice: a working /18 inside a commercial network, still registered to the amateur body, with reverse names under an operator's callsign.
• One hundred and fifteen prefixes for 137,000 addresses means an average announcement of about a /21. A wireless network built tower by tower accumulates small blocks and announces each as it is deployed.
• The two octet orders come from two different generations of zone tooling, both still authoritative for parts of the same network.
