About this ASN.

Updated  ·  Confidence: Low  ·  3 sources  ·  How this page is checked

AS1377 is an ASN in the ARIN-allocated IANA block 1–1876. In the combined Route Views observation at 2026-11-03 14:00 UTC, no IPv4 or IPv6 prefixes, addresses, or AS_PATH neighbours were observed. This snapshot does not identify the ASN’s operator or establish whether it is currently in use outside the observed data.

The routing counts combine route-views2 and route-views6. They describe that single observation across both collectors, not separate measurements from each collector. Zero prefixes and neighbours means none appeared in this snapshot; it does not establish that the ASN is dormant, withdrawn everywhere, or inactive.

For identification, first compare the ASN with authoritative registry records and any network documentation supplied by the organization under investigation. For routing triage, check later and additional public BGP observations for announcements and AS_PATH adjacencies, then validate any findings with the relevant network operator. Treat an AS_PATH neighbour as an observed route adjacency, not proof of a commercial peer, upstream, or customer relationship.

Observed routing
Zero IPv4 prefixes, IPv6 prefixes, IPv4 addresses, and AS_PATH neighbours in the combined observation at 2026-11-03 14:00 UTC across route-views2 and route-views6.
Identification
Operator and network identity are unknown from the supplied evidence.
Triage
Compare authoritative registry records and later routing observations; do not infer inactivity from this single snapshot.
