AS1103
AS1103 announces 100 IPv4 and 4 IPv6 prefixes and peers with 41 other networks.
Summary
- // analyst note
- Routing observations are the combined snapshot from route-views2 and route-views6 at 2026-11-03 14:00 UTC; observed AS_PATH neighbours are not verified commercial peers or upstreams.
About this ASN.
AS1103 is assigned through ARIN and had active route visibility in the combined Route Views snapshot at 2026-11-03 14:00 UTC. That snapshot, collected by route-views2 and route-views6 together, contained 100 IPv4 prefixes and 4 IPv6 prefixes for the ASN. The supplied evidence does not identify its operator, country, website, or network type.
The snapshot also recorded an estimate of 7,204,096 IPv4 addresses and 42 observed AS_PATH neighbours. These measurements describe this combined observation at that timestamp; they do not establish commercial peering, upstream or customer relationships, or current conditions beyond the snapshot.
For identification, compare the ASN and announced prefixes with independently documented operator records, then check whether the same routes appear in later observations. Treat the listed neighbours as routing-path clues only. The registry block indicates ARIN assignment authority for this range, but does not establish an individual assignment, deployment, traffic prevalence, or safety.

Who it talks to.
Neighbours observed by RouteViews at 2026-11-06, lowest ASN first. Relationships are inferences from the CAIDA AS Relationships Dataset, 2026-08-01, and establish no commercial arrangement; a dash means the inference did not resolve.
