As of 10th November 2026, AS18001 (Dialog Axiata PLC.), an access network registered in Sri Lanka with APNIC, originates 124 IPv4 prefixes covering 363k addresses and 134 IPv6 prefixes. By IPv4 address space that makes it the 873rd-largest of the 80,723 networks we see originating IPv4, and the 2nd-largest of 22 in Sri Lanka. It is seen behind 57 upstream networks, most often AS45489 (Sri Lanka Telecom PLC) and AS4637 (Telstra International Limited), and in front of 11 downstream networks. Every one of its announcements has a valid RPKI ROA, and none are RPKI-invalid. 94% of its routes reach at least 90% of full-feed peers.

Upstream graph

The networks AS18001 is seen behind, one and two hops out, drawn from real AS paths.

Networks observed one and two hops upstream of AS18001 in real AS paths. A thicker line means more vantage points saw that adjacency, so weight tracks how well attested it is — not how much traffic it carries. Adjacency is an observation; whether it is a transit purchase or a settlement-free peering is an inference, and is labelled as one wherever we show it.
