AS1638

AS1638’s registered organization and current operator are unknown; in the combined Route Views snapshot, it announced two IPv4 prefixes and no IPv6 prefixes. This is a limited observation at 2026-11-06 20:00 UTC, not evidence that the ASN is dormant or inactive. The IANA number-block entry identifies ARIN as the allocating RIR, but does not identify an individual assignee.

The combined snapshot estimates 1,280 IPv4 addresses and records one observed AS_PATH neighbour, AS237. That adjacency does not establish a verified peer, upstream, customer, or provider relationship. The counts describe the joint observation across route-views2 and route-views6; they are not separate counts for each collector.

For identification, compare the two observed IPv4 prefixes with current routing data and authoritative registration records, then check whether an independently documented organization explicitly links itself to AS1638. Treat missing IPv6 routes and any absent observations as snapshot limits, not proof of non-use. Routing evidence alone cannot establish ownership, location, traffic prevalence, or safety.

Observed routing

Two IPv4 prefixes and zero IPv6 prefixes in the combined 2026-11-06 20:00 UTC Route Views observation.

Triage

Operator identity is unknown; the single observed AS_PATH neighbour is AS237 and does not verify a commercial relationship.

Identification

Compare the observed prefixes with authoritative registration records and current routing evidence before attributing the ASN to an organization.
