Unclassified RIPE Cable/DSL/ISP
Summary
MGK Fiber
isp residential fiber poland
MGK-AS is operated by MGK Fiber Sp. z o.o.
What it's used for
- The address space carries residential and business subscriber traffic, evidenced by reverse DNS records such as
92-63-36-0.ip.mgk.pland185-13-145-0.ip.mgk.pl. - The AS announces 6,144 IPv4 addresses across 3 prefixes and 2 IPv6 prefixes, while maintaining 11 observed neighbours; this ratio indicates an access network providing last-mile connectivity rather than a transit provider.
- Traffic originates from cable and DSL subscribers in the Gora Kalwaria region of Poland, consistent with the operator's role as a local ISP.
Notable
- All registrants for the announced prefixes are listed as MGK Fiber Sp. z o.o., aligning perfectly with the AS holder.
- The address inventory consists of three distinct IPv4 blocks acquired between 2009 and 2016, reflecting gradual expansion of the local network footprint.

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: 442 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.
