AS6140 TWO-P

TWO-P is Two P, a small network operator registered in Mill Valley, California. It routes its own address block along with space belonging to a handful of other organisations.

What it's used for

• Transit and hosting for a small set of networks. Its own allocation is 107.161.208.0/20 (ARIN netname TWOP-V4-20), and reverse DNS across its space resolves into a few distinct third-party domains rather than one house brand. That is the shape of a small operator carrying traffic for others.

Notable

• Several of the prefixes it announces come from 44.0.0.0/8, the AMPRNet range administered by Amateur Radio Digital Communications. That block is set aside for amateur-radio digital networking, so a slice of what this ASN routes is ham-radio infrastructure rather than commercial hosting. That is an unusual thing to find in a four-digit AS.
• The overall footprint is tiny, a few thousand addresses, so this is an independent operator rather than a commercial provider of any scale.
• The ARIN registration dates to 2011, so the low AS number is a reissue to a modern holder and implies no early-internet history.

Interesting

• The mixture of a commercial /20, legacy /24s and AMPRNet space under one small California ASN is a good illustration of how much of the routing table is run by individuals and very small outfits rather than by companies.
