AS688

AS688 (RECNET-AS) is a U.S. federal government autonomous system registered to the Bureau of Reclamation, an agency of the Department of the Interior, and it currently announces zero prefixes. Multiple independent routing sources agree the AS has been fully withdrawn from the global routing table since late January 2025, even though its ARIN registration remains formally active.

The ASN was registered with ARIN on 1990-06-25 and last updated 2024-09-23. Historically it announced two IPv4 blocks tied to the Bureau's wide-area network — 137.77.0.0/17 and 140.215.0.0/16, roughly 98,304 addresses combined — but neither is visible in the current routing table.

CAIDA ranks AS688 at 79,459 with a customer cone limited to itself: zero prefixes, zero addresses. No upstreams, downstreams, or active peers appear in CAIDA's ASN-degree data or bgp.tools; the only documented BGP relationship is a historical peering with AS22284, another Department of the Interior ASN. No PeeringDB record exists for AS688 (404 on both the profile and API lookup), consistent with a non-peering internal government network rather than a commercial operator.

AS688 supports the Bureau of Reclamation's internal IT and WAN infrastructure — the agency manages dams, hydroelectric power, and wholesale water delivery across the western United States — rather than acting as a transit, hosting, or content network. The registrant address is the Bureau's IT Services Division in Denver, Colorado.

Analyst note

RIR-active but routing-dormant since Jan 2025. The ARIN top-level autnum registration date (1990-06-25) is the true allocated_date; several nested contact/org-record dates present in the raw RDAP response (e.g. BORAB-ARIN POC 2015-02-20, BORWA-ARIN POC 2024-07-17, RINEY2-ARIN POC 2014-12-10, UBR-Z org record 2024-09-16) are decoys belonging to sub-records and were not used.
