Summary
FUZ
isp residential regional cable
The AS handle FUZ-AS is held by Adam Rojek, operating as FUZ.
What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS records such as
host-37-254.wyszkow.fuz.pland netnamesPL-FUZandPL-FUZ-20180910. - The network announces 4352 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with 15 observed routing neighbours, indicating a regional access provider rather than a transit carrier.
- Traffic from this AS consists of subscriber eyeballs for cable and DSL connections in the Wyszkiw region of Poland.
Notable
- All registrants for the announced prefixes are listed as
ADAM ROJEK, consistent with the AS holder. - The address inventory is subdivided into multiple /24 and /23 blocks alongside a /21 and /22, reflecting site-by-site segmentation for a local ISP.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
