Unclassified ARIN
Summary
Westel, Inc.
isp legacy
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.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-27, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
