Summary

State Institute for Drug Control

Czechia · AI-generated

government pharma regulatory czechia

The AS handle SUKL_AS is held by State Institute for Drug Control.

What it's used for

  • The address space carries internal network traffic for the State Institute for Drug Control, as indicated by the netname CZ-SUKL-20100825 and registrant State Institute for Drug Control; SUKL admin.
  • The inventory consists of 2048 IPv4 addresses within a single /21 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, isolated government network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications, regulatory data processing, and administrative services for the Czech national drug control authority.

Notable

  • The registrant State Institute for Drug Control; SUKL admin aligns directly with the AS holder, confirming consistent ownership.
  • The address inventory is compact and singular, consisting of one contiguous IPv4 block and one IPv6 prefix, typical of a single-site government agency.

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: 453 networks and 1,848 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.
