AS813

AS813 is a small, low-activity legacy autonomous system — registered under ARIN as UUNET-CANADA and now operated under the Verizon Business network — that announces just two IPv4 /24 prefixes and no IPv6 today. It is not dormant in the AS181 sense (it does route live traffic), but its footprint is tiny: roughly 512 IPv4 addresses total, with a single visible upstream.

The ASN traces back to UUNET's historical Canadian backbone, absorbed into MCI/WorldCom and later Verizon. ARIN RDAP records a top-level registration (allocation) event of 2002-05-21 and a last-changed event of 2022-05-31; the registrant organization is MCI Communications Services, Inc. (d/b/a Verizon Business, ARIN org handle MCICS), under parent Verizon Communications Inc., with an Ashburn, VA address in RDAP entities.

Both bgp.he.net and bgp.tools show AS813 announcing only 204.92.101.0/24 and 204.92.184.0/24, with AS11486 (also Verizon Business) as its sole observed upstream/provider — consistent with a folded-in legacy stub rather than an independently peering network. No dedicated PeeringDB listing exists (peeringdb.com/asn/813 returns 404), and Verizon's own published Interconnection Policy for Internet Networks names only AS701, AS702, and AS703 — not AS813. CAIDA AS Rank places it 54406 globally, with a customer cone of just itself — 1 ASN, 2 prefixes, 512 addresses — and an asnDegree of provider 1, peer 0, customer 0, consistent with a single upstream and no distinct peering relationship.

RPKI coverage for the two announced prefixes shows 0 valid and 0 invalid origins on bgp.he.net — meaning no ROA coverage was found, not that an invalid origin is being announced.

RPKI

0 RPKI-valid and 0 RPKI-invalid origins reported for the two announced prefixes — no ROA coverage found, not an active invalidity [Confirmed] — https://bgp.he.net/AS813

Notable usage

registry name UUNET-CANADA ties AS813 to UUNET's historical Canadian internet backbone, later absorbed into MCI/WorldCom and then Verizon following Verizon's 2006 MCI acquisition; today it is a small, near-dormant announcement under the Verizon Business umbrella

Analyst note

encountered as a small legacy Verizon Business ASN (former UUNET Canada backbone identity) that still routes a minimal footprint — two /24s, one upstream — rather than being fully dormant; no independent peering policy or PeeringDB presence, and no public abuse signal found.
