Summary

Inform-Service TV

Uzbekistan · AI-generated

isp cable uzbekistan

ISTV-AS is operated by Inform-Service TV Ltd.

What it's used for

  • The address space carries residential and business internet access, evidenced by reverse DNS entries like ip1023.istv.uz and ip1534.istv.uz within the ISTV-NET netname.
  • The AS announces 8,192 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic consists of subscriber internet and television services, as the operator identifies as a "next-generation provider" offering internet and TV in Tashkent.

Notable

  • Registrants for the 31.135.208.0/21 and 31.148.160.0/21 prefixes match the announcer, listing Inform-Service TV Ltd. NOC, while the 95.46.80.0/20 prefix is registered to ALFA TELECOM s.r.o. under the netname CZ-ALFATELECOM-20081201.
  • The inventory includes a mix of prefixes, with two blocks directly registered to the operator and one block registered to a Czech entity, suggesting leased or acquired address space.

Reputation

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.
