AS93

AS93 is a legacy number that has been reassigned: RFC 1020 (1987) and RFC 1166 (1990) recorded it as "FORD-AS," Ford Motor Company's allocation, but it was later reclaimed and reassigned to NTT America, Inc. (OrgId NTTAM-1), carrying the handle "NTTA-93." The ARIN RDAP RegDate is 2000-03-29 — about thirteen years later than its 1986-era siblings, confirming the reassignment. Today it is a small legacy NTT-held number, distinct from NTT's main backbone AS2914 (which accepts and announces AS93 as a customer/downstream); bgp.he.net notes AS93 "announces bogons." For triage the famous Ford association is obsolete — this is now an NTT-administered small AS, and its routing should be treated as carrier-internal/customer. No notable public abuse signal was found as of June 2026 beyond the bogon-announcement flag.

A recycled legacy number — the famous Ford association is obsolete. Now an NTT-administered small AS; treat routing as carrier-internal/customer. Note the "announces bogons" flag on HE.
