government infrastructure slovakia

GOVSK-AS is operated by the National Agency for Network and Electronic Services (NASES).

What it's used for

  • The address space carries government services, evidenced by netnames govnet-sk and SK-NASES-20150812 registered to gov.sk and the agency itself.
  • One prefix, 91.199.31.0/24, is registered to the Slovak Hydrometeorological Institute under netname SK-SHMU-PI-001, indicating shared government infrastructure.
  • The AS announces 2560 IPv4 addresses across 4 prefixes and 3 IPv6 prefixes, with 11 observed neighbours, suggesting a role focused on internal government connectivity rather than large-scale transit or consumer access.

Notable

  • Registrants align with the announcer for most prefixes, with gov.sk and the National Agency for Network and Electronic Services listed for the majority of the inventory.
  • The address inventory is finely subdivided, with distinct blocks assigned to specific government entities like the Hydrometeorological Institute, reflecting a segmented internal corporate 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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
