About this ASN.

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

AS1387 is an autonomous system whose operator and registered name are unknown from the supplied evidence; a routing snapshot shows one IPv4 prefix and one IPv6 prefix. This is a limited observed presence, not evidence of the network’s current operator, purpose, safety, or broader activity.

In the combined RouteViews observation at 2026-11-03 14:00 UTC, collected from route-views2 and route-views6, the IPv4 address estimate is 256 and one AS_PATH neighbour was observed: AS701. That adjacency does not establish a verified peer, upstream, customer, or provider relationship.

IANA places AS1387 in resource block 1-1876, described as assigned by ARIN. This identifies the allocating regional registry for the block, not an individual assignment record or present-day organization. For investigation, compare fresh routing observations over time and inspect the announced prefixes and their origin paths; seek an authoritative ASN-to-organization record before assigning an operator or location.

Identity
Operator, ASN name, country, and network type are Unknown from the supplied evidence.
Routing status
One IPv4 prefix and one IPv6 prefix were observed in the combined RouteViews snapshot at 2026-11-03 14:00 UTC.
Triage
A single timestamp and one observed AS_PATH neighbour are insufficient to establish operating status or commercial relationships.
