AS815

AS815 is a legacy autonomous system originally assigned to UUNET Canada Inc. and now registered to Verizon Business, but it is dormant in the global routing table — RIPEstat and CAIDA both show it announcing zero IPv4 and zero IPv6 prefixes today, with no visible BGP peers, upstreams, or customers.

The ASN's history traces UUNET's rise as one of the first major commercial ISPs. UUNET Canada's national IP backbone ran under this number before UUNET was absorbed into MFS/WorldCom, then MCI, and finally acquired by Verizon in 2006 to form Verizon Business — the current ARIN registrant of record (org handle MCICS).

ARIN's RDAP record remains administratively active for AS815 (status: active, last changed 2022-05-31), but the last routing-table announcement on record dates to 2002-02-19 (216.95.232.0/24). CAIDA ranks it 79,459 with a customer cone limited to the ASN itself — zero prefixes, zero addresses, zero degree in any direction.

No PeeringDB profile exists for AS815 (a direct lookup returns 404), and no AS815-specific peering policy was found. Verizon Business does publish a corporate peering policy, but it scopes itself explicitly to its three active regional backbone ASNs — AS701 (Americas), AS702 (Europe), and AS703 (Asia-Pacific) — and never names AS815, so whether that policy would govern this ASN if it were reactivated is unconfirmed.

Exposure

AS815 originates no live prefixes, so it presents no current routing attack surface (no announced space to hijack or misroute).

Abuse signal

No notable public abuse report names AS815 or UUNET-Canada specifically as of 2026-08-01; a direct Spamhaus ASN-DROP query for AS815 returned no result.

Related-ASN caution

Distinct Verizon/UUNET-lineage ASNs carry documented abuse history — Spamhaus's 2016 report on cybercrime routing names AS7046 (originally UUnet Technologies), not AS815 — so that history should not be conflated with this ASN.

RPKI

Not evaluable; with zero announced prefixes there are no ROAs to validate against.

Operator

Verizon Business (org handle MCICS; current ARIN registrant); RDAP name field retains the legacy label UUNET-CANADA, reflecting origin as UUNET Canada Inc. [Confirmed] — rdap.arin.net/registry/autnum/815

Country / RIR

US, ARIN [Confirmed] — ARIN RDAP autnum record

Allocated

2002-05-21 (ARIN RDAP top-level autnum registration event); last changed 2022-05-31 [Confirmed] — rdap.arin.net/registry/autnum/815

Org status

active per ARIN (status: active); registrant Verizon Business, a business unit of Verizon Communications Inc., HQ Ashburn, VA; no indication of retirement or return to IANA [Confirmed] — rdap.arin.net/registry/autnum/815

Contacts

abuse-mail@verizonbusiness.com; abuse@verizon.com [Confirmed] — RIPEstat abuse-contact-finder

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found specifically for AS815 as of 2026-08-01; distinct Verizon/UUNET-lineage ASNs (e.g. AS7046, formerly UUnet Technologies) do carry documented abuse history and should not be conflated with AS815

Network & routing

Network type

legacy/historical UUNET Canada national IP backbone; dormant today (zero announced prefixes) — Verizon's active global backbone routing runs under AS701/AS702/AS703, not AS815 [Confirmed]

Size

dormant — 0 IPv4 prefixes / 0 addresses and 0 IPv6 prefixes; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses; CAIDA AS rank 79,459 [Confirmed] — RIPEstat routing-status, CAIDA AS Rank (2026-08-01)

Routing/peering

NOT announced — 0 RIS peers currently seeing it (0/328 v4, 0/322 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB entry (404); last historical announcement was 216.95.232.0/24, last seen 2002-02-19 [Confirmed]. Verizon's active backbone (AS701/702/703) peering policy does not mention AS815 [Confirmed for policy scope; Unknown whether it would apply to AS815]

RPKI

not assessable — AS815 announces no prefixes, so there are no ROAs to validate; RIPEstat's rpki-validation check requires a prefix and was skipped for this reason [Confirmed]

Notable usage

historically the AS number for UUNET Canada's national IP network, a major early commercial ISP backbone; folded into Verizon Business after the 2006 acquisition; no current observable usage since the AS is dormant at the BGP level [Likely] — bgp.he.net/AS815, rdap.arin.net/registry/autnum/815

Related ASNs

AS701, AS702, AS703 (Verizon Business's active regional backbones, named in its published peering policy); AS7046 (originally UUnet Technologies, a distinct Verizon/UUNET-lineage ASN with documented abuse history) [Confirmed]

Analyst note

Encountered as an administratively active but operationally dormant legacy ASN. WHOIS/RDAP resolves to Verizon Business under the historical UUNET-CANADA label; live routing has not been observed since 2002, and Verizon's current active backbone runs under AS701/AS702/AS703. Clean — no abuse signal specific to this ASN.
