Summary

Dialog Axiata PLC

Sri Lanka · AI-generated

mobile residential isp sri-lanka

The AS handle DIALOG-AS is held by Dialog Axiata PLC.

What it's used for

  • The address space carries mobile and broadband access traffic, evidenced by the reverse DNS record pool-512k-ind-bb.wow.lk and netnames DIALOG-LK and MTT-LK.
  • With 184,320 IPv4 addresses announced across 69 prefixes and 183 observed neighbours, the high neighbour count relative to the address block size indicates a transit and peering role typical of a national carrier.

Notable

  • Registrants are consistent with the announcer, primarily listing Dialog Axiata Plc under IRT-DIALOG-LK, with some blocks registered to MTT Network (Pvt) Ltd under IRT-MTT-LK.
  • The inventory includes legacy prefixes from MTT Network, reflecting the historical merger between Dialog and MTT in Sri Lanka.
  • The address inventory is finely subdivided into numerous /19, /20, and /21 blocks, characteristic of a large-scale access network managing distinct customer pools.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 442 networks and 1,783 prefixes, as published 2026-10-20. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
