AS32837 WCL-50-AS - Williams & Connolly, LLP
Unclassified ARIN
Summary
Williams & Connolly, LLP
business legal corporate internal
The AS handle WCL-50-AS is held by Williams & Connolly, LLP, a prominent Washington, D.C.-based law firm.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by registrant netnames
TWTC-NETBLK-19andALLIED-I95-NET7and reverse DNS entries pointing toi95.net. - The AS announces 512 IPv4 addresses across 2 prefixes with 4 observed neighbours, a ratio consistent with a small, self-contained internal network rather than a transit or access provider.
Notable
- The registrants for the announced prefixes are Level 3 Parent, LLC and Allied Telecom Group, LLC, which differ from the AS holder, indicating the firm leases its address space from telecommunications providers.
- The address inventory consists of two /24 blocks, one from each registrant, reflecting a segmented corporate estate rather than a contiguous allocation.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
