Summary

Metropolitní síť Humpolec

Czechia · AI-generated

isp fiber residential czech

The AS handle METRO-HU is held by Metropolitní síť Humpolec spol. s r.o.

What it's used for

  • The space carries residential and business internet access, evidenced by the netname CZ-METROPOLITKA-20171212 and the operator's description of building a metropolitan network via optical fibre.
  • The inventory consists of 1024 IPv4 addresses in a single /22 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a local access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and local business endpoints connected via the operator's fibre infrastructure in Humpolec.

Notable

  • The RDAP registrant Metropolitni sit Humpolec spol. s r.o. matches the AS holder exactly.
  • The address inventory is compact, consisting of a single contiguous IPv4 block and one IPv6 prefix, typical for a small regional ISP.

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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
