AS284

AS284 is a legacy autonomous system number registered under ARIN and held today by MCI Communications Services, Inc. d/b/a Verizon Business. Its registry name, UUNET-IPV6, reflects its original role as the IPv6 routing identity of the legacy UUNET backbone — UUNET being one of the first commercial Internet service providers, founded in 1987, later absorbed into MFS/WorldCom and then into Verizon Business. The key triage point for AS284 is that it is operationally dormant: every routing source consulted (RIPEstat, CAIDA AS Rank, bgp.he.net, bgp.tools) agrees it announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers, zero upstreams, and a singleton customer cone. RIPEstat routing history shows AS284 was active until roughly April 2012, when its last IPv6 prefix (2600:804:5::/48) was withdrawn; its first IPv6 prefix (2001:48b8::/32) was seen around April 2007. Its CAIDA AS rank of 79,459 sits near the bottom of the global ranking, consistent with complete routing inactivity. Verizon Business's active operational routing runs under AS701 (US), AS702 (Europe), and AS703 (Asia-Pacific). RPKI posture cannot be assessed for AS284 because there are no active originations and therefore no ROAs. No notable public abuse signal was found as of June 2026 — not in Spamhaus ASN-DROP, CleanTalk, AbuseIPDB, FraudGuard, or NANOG archives — consistent with a clean, dormant ASN held by a respected Tier-1 carrier.

Operator

MCI Communications Services, Inc. d/b/a Verizon Business (ARIN org MCICS; ASN name UUNET-IPV6) [Confirmed] — ARIN RDAP, ipinfo.io/AS284, bgp.tools/as/284

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP, RIPEstat as-overview (resource=284)

Allocated

1989-05-11 (ARIN registry date — one of the earliest ASNs assigned; a first-party RIR registry fact, NOT an IEEE date); last changed 2022-05-31 [Confirmed] — ARIN RDAP autnum top-level events (A2, A3, A5 concur)

Org status

active ARIN allocation maintained by Verizon Business, but ASN is operationally dormant — not in the global routing table, originating zero prefixes as of 2026 [Confirmed] — ARIN RDAP, bgp.he.net/AS284, ipinfo.io/AS284

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-06-25 — not on Spamhaus ASN-DROP, CleanTalk, AbuseIPDB, FraudGuard, or in NANOG archives; the well-documented historical UUNET routing leak involved AS701, NOT AS284 [Likely — based on web-indexed search, no live blocklist API query] — spamhaus.org/drop/asndrop.txt, cleantalk.org/blacklists/asn, kentik.com BGP-incidents history

Network & routing

Network type

Tier-1 carrier / backbone (legacy IPv6 ASN under Verizon Business); AS284 itself is dormant — active backbone runs under AS701/AS702/AS703 [Confirmed] — bgp.he.net/AS284, bgp.tools/as/284, en.wikipedia.org/wiki/UUNET

Size

dormant — 0 IPv4 prefixes / 0 IPv4 addresses and 0 IPv6 prefixes announced; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses [Confirmed] — RIPEstat routing-status / CAIDA AS Rank / bgp.he.net / bgp.tools (2026-06)

Routing/peering

NOT announced — 0 RIS peers seeing it (v4 and v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no upstreams or peers visible in any source [Confirmed]. Verizon Business's active ASNs (AS701/702/703) run a Selective peering policy via peering@verizonbusiness.com [Likely — policy applies to the active ASNs, not dormant AS284]

Historical routing

first IPv6 prefix 2001:48b8::/32 seen ~April 2007; last prefix 2600:804:5::/48 withdrawn ~April 2012; unannounced since [Confirmed] — RIPEstat routing-status (resource=284)

RPKI

not assessable — AS284 announces no prefixes, so there are no ROAs to validate [Confirmed] — A3 (no prefix to validate)

Notable usage

AS284 (UUNET-IPV6) was the legacy IPv6 routing identity of the UUNET backbone (founded 1987), absorbed into MFS/WorldCom (1996) and then Verizon (2006). Dormant since ~2012; active Verizon Business routing is under AS701 (US), AS702 (EU), AS703 (APAC) [Confirmed for history/active ASNs; bgp.he.net, en.wikipedia.org/wiki/UUNET]

Related ASNs

AS701 (Verizon Business US backbone), AS702 (Europe), AS703 (Asia-Pacific) [Confirmed — active operational ASNs]

Analyst note

Encountered as a dormant legacy ASN registered to a Tier-1 operator. WHOIS resolves to Verizon Business, but live routing is under AS701/702/703, not AS284. Clean, inactive ASN.
