business latvia marketing

The AS handle LATVIJASTALRUNIS is held by heise marketing SIA.

What it's used for

  • The space carries a single IPv4 prefix, 213.175.78.0/24, with the netname Latvijas-Talrunis-TETLV and registrants TET HostMasterTL and LTC Hostmaster.
  • The network announces 256 IPv4 addresses across 1 prefix and has 2 observed neighbours, indicating a small-scale business or internal corporate estate rather than a transit or large access network.
  • Traffic from this AS consists of web and API endpoints for a digital marketing agency operating in Riga, Latvia.

Notable

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
