About this network

WESTEL-ASN1 is Westel, Inc., a privately held telecom provider headquartered on Park 35 Circle in Austin, Texas, selling bundled voice, data and internet access. ARIN's ASN record dates from December 2010 and was last touched in 2012.

What it's used for

Access-provider space, carried on a small inventory. RIS sees eight v4 prefixes totalling 3,328 addresses and no IPv6, with a single observed neighbour. The one-neighbour count is the important part: whatever Westel sells, it is not wholesale transit — a carrier peers with hundreds of ASes, and this AS reaches the internet through one adjacency. The picture is a regional provider announcing its own customer-facing blocks through an upstream.

Notable

Every prefix in the RIS window is registered in ARIN to Westel, Inc., though under a spread of netname handles — WESTEL, WESTEL1-76--24, WESTEL2-12--23 and a FIBRCOM1-84-85 block. Varied netnames with one consistent org is normal accretion from allocations picked up over the years (the FIBRCOM name hints at space that arrived with a business rather than being allocated fresh). None of this resembles the multiple-unrelated-registrant pattern that marks leased or brokered space.

Interesting

What the space actually carries is not observable here — no PTRs came back on the addresses sampled, which is a sample and not a finding, so it supports no conclusion either way. Westel's own material describes both business and residential broadband, so the customer mix behind these eight prefixes is best treated as unconfirmed rather than guessed at.
