Summary

Blicnet

Bosnia and Herzegovina · AI-generated

isp residential cable bosnia

The AS handle BLICNET-AS is held by Blicnet d.o.o. Banja Luka.

What it's used for

  • The address space carries residential broadband access, evidenced by reverse DNS entries such as cable.dyn.broadband.blic.net and pppoe.dyn.broadband.blic.net.
  • With 96000 IPv4 addresses announced across 43 prefixes and only 5 observed neighbours, the ratio indicates an access/eyeball network rather than a transit provider.

Notable

  • Registrants for the majority of prefixes are consistent with the announcer, listed as "BLICNET Internet Team - Ripe; Blicnet d.o.o. Banja Luka".
  • One prefix, 94.250.96.0/20, has a different registrant ("MTEL Abuse contact") and netname "SUPERNOVA-NET", suggesting leased space or historical acquisition.
  • The inventory includes a single IPv6 prefix, 2a00:1a98::/32, alongside the substantial IPv4 block.

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 1,775 prefixes, as published 2026-10-11. 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.
