Summary

FORWEB

Poland · AI-generated

isp residential cable regional

FORWEB is operated by "FORWEB" S.C. Monika Bodetko, Tomasz Pawlowski.

What it's used for

  • The address space carries customer access traffic, evidenced by netnames like PL-FORWEB-CUSTOMERS and reverse DNS entries such as ip-95-175-1-0.cust.forweb.pl and ip-95-175-23-255.4web.pl.
  • With 11,008 IPv4 addresses announced across 9 prefixes and 19 observed neighbours, the ratio indicates a regional access provider rather than a transit hub.

Notable

  • Registrants for all major prefixes align with the AS holder, including "FORWEB" S.C. Monika Bodetko, Tomasz Pawlowski and FORWEB ip address and domain administration.
  • The inventory consists of 9 IPv4 prefixes with no IPv6 prefixes in the inventory, reflecting a legacy IPv4-only deployment.
  • One prefix, 217.11.135.0/24, is registered under the netname RDI-RZGOW, which differs from the primary FORWEB branding.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
