isp residential cable regional

The AS handle FIBERLINK-AS is held by Fiberlink Sp. z o.o.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries like host-176-104-181-254.fiberlink.pl and netnames such as FIBERLINK and ETERNAL.
  • The AS announces 7,936 IPv4 addresses across 9 prefixes and maintains 13 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
  • Traffic from this AS consists of subscriber eyeballs for internet, television, and telephony services, as Fiberlink is a Polish technology company providing these multimedia services to households.

Notable

  • Registrants largely align with the announcer, with most prefixes registered to FIBERLINK Sp. z o.o., though the largest block 176.104.176.0/21 is registered to ETERNET Sp. z o.o. and 91.230.98.0/23 to NETRIC Zbigniew Szaranski.
  • The inventory is composed of a mix of /22, /23, and /24 blocks, with the largest allocation being the /21 prefix.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
