isp czech fiber wifi

NETSERV-AS is operated by NetSERV, s.r.o., a telecommunications provider based in Mikulov, Czechia.

What it's used for

  • The address space carries residential and small business internet services, evidenced by the netname CZ-NETSERV-20240110 and the operator's provision of "FreeBand" optical internet and Wi-Fi solutions.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for local internet access, including broadband and wireless connectivity for the Mikulov region.

Notable

  • The registrant NetSERV, s.r.o. matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single /24 IPv4 block and one /29 IPv6 prefix, representing a compact, locally focused 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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
