Czechia · AI-generated

MASTER_IT_TECHNOLOGIES is operated by Master IT Technologies, a.s.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by reverse DNS entries pointing to masternet.cz and masterit.cz, as well as netnames CZ-MITT-20081113 and Master-IT-CZ.
  • The AS announces 3072 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small-scale internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers and IT service endpoints for Master IT Technologies, a provider of system integration, IT security, and outsourcing services for medium and large companies.

Notable

  • All registrants for the announced prefixes are listed as MASTER IT Technologies, a.s., fully agreeing with the AS holder.
  • The address inventory is finely subdivided into six IPv4 blocks within the 94.229.80.0/22 range, consistent with site-by-site segmentation for an internal corporate network.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
