Summary

Estonia · AI-generated

isp residential estonia access

FILL is operated by Fill Networks OU.

What it's used for

  • The address space carries residential broadband access, evidenced by reverse DNS entries such as pool-91-146-79-255.bng1.fill.ee and pool-185-153-145-0.bng1.fill.ee, which indicate Broadband Network Gateway (BNG) pools.
  • The AS announces 9,216 IPv4 addresses across 2 prefixes in Estonia, with only 1 observed neighbour, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
  • Traffic consists of subscriber eyeballs for wired, wireless, and satellite telecommunication services provided by the operator in Narva, Estonia.

Notable

  • Registrants for both announced prefixes (EE-FILLNETWORKS-20110908 and EE-FILLNETWORKS-20160524) align with the AS holder, Fill Networks OU.
  • The inventory consists of two distinct IPv4 blocks: a /19 and a /22, both located in Estonia.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
