AS691

AS691 is a dormant legacy ASN registered to the University of Prince Edward Island (UPEI) that currently announces zero IPv4 and zero IPv6 prefixes, leaving it inactive on the public Internet despite carrying an Active status at ARIN today.

ARIN RDAP records the ASN's registered name as PEINET-AS, held by UPEI at 550 University Avenue, Charlottetown, Prince Edward Island, Canada. The autnum's top-level registration event dates to 1990-07-23, with a last-changed event of 2020-10-29 — two independent research angles (operator lookup and routing lookup) agree on this pairing, so it is treated as confirmed rather than the 1989-12-03 date that appears only on a nested registrant-entity record.

Routing data corroborates the dormancy from multiple independent sources. RIPEstat shows AS691 seen by 0 of 325 IPv4 and 0 of 321 IPv6 RIS peers; CAIDA ASRank places it around #79459 globally with zero customer, peer, and provider relationships and a customer cone limited to itself; Hurricane Electric's looking glass independently confirms 0 announced prefixes in both address families. No PeeringDB record exists for AS691, and no peering policy is published anywhere.

UPEI's own site (upei.ca, upei.ca/itss) describes general campus IT support rather than a dedicated network-operations or peering microsite, consistent with an academic institutional network rather than a commercial ISP or transit provider. No notable public usage, outage, or community discussion of AS691 was found in NANOG archives or elsewhere.

Analyst note

AS691 (PEINET-AS) is a dormant legacy ASN held by a Canadian university; RDAP status is active but no live routing is observed anywhere. Two independent angles (operator and routing) agree on the 1990-07-23 allocation date, avoiding the decoy 1989-12-03 date found only on the nested UPEI registrant-entity record.
