AS5

AS5 is a legacy single-digit allocation that today is registered under ARIN to WFA Group LLC, a New Hampshire LLC — not to Symbolics, Inc. The ASN retains the historical AS-name handle SYMBOLICS, which is the source of frequent confusion: Symbolics, Inc. was the MIT-AI-Lab-spinoff Lisp-machine manufacturer that registered symbolics.com on March 15, 1985, the first-ever .com domain (the domain was separately sold in August 2009 to XF.com Investments; the ASN is a distinct asset). The current holder, WFA Group LLC (org RegDate 2019-11-04, tech/abuse POC John C. Mallery, a long-time MIT CSAIL research scientist), announces just four IPv4 /24s (1,024 addresses) of the historic 192.10.x "Symbolics" space, with no IPv6, and CAIDA records it as a pure stub (#78,889, zero-size customer cone). For triage the key point is that the famous "first .com" trivia attaches to the domain and the old company, not to who controls AS5 today — a reference page should state plainly that AS5 is currently registered to WFA Group LLC, historically the SYMBOLICS allocation. The 1984-02-02 ARIN RegDate is among the earliest in the registry. No notable public abuse signal was found as of June 2026.
