Possibly related to this organisation

what's this?

Same operating domain slt.lk

Separately-registered clusters whose addresses resolve (reverse DNS) under the same domain as this one — strong evidence they are the same organisation, even where the names differ. Namesakes on other domains are excluded.

ORG-SLTL1-AP 3 blocks on slt.lk

Same name family

Separately-registered clusters whose names share “Sri Lanka” — often per-country or per-system registrations of the same brand, occasionally a different organisation sharing the name. Not counted in this organisation's own footprint.

SRI-LANKA-SG 1 blocks

Sub-allocations under carriers

IP blocks an ISP reassigned to a similarly-named customer — decoded from the ISP's own naming convention, not a direct registration.
