Summary

mirnet s.r.o.

Czechia · AI-generated

residential isp czechia local

ASMIRNET is operated by mirnet s.r.o.

What it's used for

  • The space carries local internet access for the Nymburk region, as indicated by the netname MIR-NET and the operator's history as the first provider in Nymbursko.
  • The AS announces 1024 IPv4 addresses in a single prefix (91.227.232.0/22) with 1 observed neighbour, a ratio typical of a small regional access network.
  • Traffic consists of subscriber eyeballs for local residential and small business customers in the Nymburk area.

Notable

  • The RDAP registrant mirnet s.r.o. matches the AS holder and the netname MIR-NET.
  • The address inventory is a single contiguous /22 block, consistent with a small, self-contained local ISP estate.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
