isp business

One Ukrainian /22 whose only answering address is called webmaster.

What it's used for

  • Internet access. 1,024 addresses in a single /22, one observed BGP neighbour, and no IPv6 announced.

Notable

  • The whole inventory is 194.42.192.0/22, under the netname TCOM — four letters, no country prefix and no date.
  • One sampled address answers webmaster.uz.ua.

Interesting

  • TCOM predates the convention almost every other block in this range follows. Netnames became COUNTRY-COMPANY-DATE because registries needed them to be unique and sortable; the ones that are just a contraction of the company name were registered before anybody needed to sort them.
  • uz.ua is the regional domain for Uzhhorod, in the far west of Ukraine, so the network is named for a city rather than a company in the only place a user would see it.
  • Naming a machine webmaster puts a job title where a hostname belongs. It comes from the era when one box was the web server, the mail server and the thing the webmaster logged into, and the name that stuck was the person's rather than the machine's function.

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 1,783 prefixes, as published 2026-10-17. 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.
