AS762

AS762 is a dormant legacy autonomous system registered under ARIN to Wellfleet Communications, Inc., a 1990s router-vendor whose registration has carried zero live route announcements since 2001 and has no active operating successor today.

Wellfleet Communications was, in its own era, a significant player: by 1993 it held roughly 14% of the global router market — the #2 vendor behind Cisco — and Fortune named it the fastest-growing U.S. company in both 1992 and 1993. That independent existence ended in October 1994, when Wellfleet merged with SynOptics Communications to form Bay Networks; Bay Networks was itself acquired by Nortel Networks in June 1998. AS762 was never reassigned to either successor and carries no operational meaning for Wellfleet, Bay Networks, or Nortel today.

Routing data across RIPEstat, bgp.he.net, bgp.tools, and CAIDA AS Rank agree the ASN announces 0 IPv4 and 0 IPv6 prefixes, is visible to 0 of roughly 330 RIS peers, and has a customer cone limited to itself (0 prefixes, 0 addresses). Its last observed announcement was 47.16.0.0/24 on 2001-11-28, after first appearing with 134.177.0.0/16 on 2000-08-18. CAIDA ranks it 79,459th globally — near the bottom, consistent with total routing inactivity.

The ARIN record itself shows administrative decay rather than active management: the abuse/admin contact is a placeholder (nobody@example.com) and the listed technical POC failed ARIN revalidation as of 2025-02-08. No official Wellfleet website remains reachable to corroborate any of this from the operator side.

Org status

ARIN registry status "active" but administratively stale — abuse/admin contact is a placeholder (nobody@example.com); technical POC (Steven Willis) unvalidated by ARIN since 2025-02-08; no successor entity operates this ASN [Confirmed] — https://rdap.arin.net/registry/autnum/762

Contacts

abuse/admin = nobody@example.com (RFC 2606 placeholder, ARIN entity CKN23-ARIN); technical POC Steven Willis, listed at an individual mailbox on the defunct wellfleet.com domain (unvalidated since 2010; the personal address is not republished here); registrant address 12 DeAngelo Drive, Bedford, MA 01730-2204

Network & routing

Network type

historic corporate/vendor ASN; not an active service-provider or transit network [Likely] — https://bgp.he.net/AS762

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses, 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — https://stat.ripe.net/AS762, https://api.asrank.caida.org/v2/restful/asns/762

Routing/peering

NOT announced — 0/330 RIS peers see v4, 0/323 see v6; first seen 134.177.0.0/16 on 2000-08-18, last seen 47.16.0.0/24 on 2001-11-28; CAIDA AS rank 79,459 [Confirmed] — https://stat.ripe.net/AS762, https://bgp.he.net/AS762, https://bgp.tools/as/762, https://api.asrank.caida.org/v2/restful/asns/762

RPKI

not assessable — AS762 announces no prefixes, so RIPEstat rpki-validation (which requires a prefix) was not run [Confirmed] — https://stat.ripe.net/AS762

Notable usage

Wellfleet Communications was the #2 global router vendor by market share (~14% in 1993, behind Cisco) and Fortune's fastest-growing U.S. company in 1992 and 1993; merged with SynOptics Communications (Oct 1994) to form Bay Networks, later acquired by Nortel Networks (Jun 1998)

Analyst note

Legacy 1991 registration held by a defunct 1990s router vendor (Wellfleet Communications → Bay Networks 1994 → Nortel Networks 1998); dormant since 2001, no reachable operator website, registry contacts are stale placeholders.
