Summary

Lanultra

Bulgaria · AI-generated

isp residential bulgaria

The AS handle LANULTRA is held by Ultra-Todor Slavov Ltd.

What it's used for

  • The address space carries residential and business internet access, evidenced by the netname BG-LANULTRA and reverse DNS entries pointing to lanultra.net.
  • The network announces 2048 IPv4 addresses across 3 prefixes with only 1 observed neighbour, a ratio that indicates an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for customers in Bulgaria, consistent with the operator's role as a local ISP.

Notable

  • All registrants for the announced prefixes are listed as Abuse-C Role with the netname BG-LANULTRA, which aligns with the announcer's identity.
  • The address inventory consists of three IPv4 prefixes: 46.254.128.0/22, 185.219.68.0/23, and 185.219.70.0/23, all located in Bulgaria.

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 1,782 prefixes, as published 2026-10-16. 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.
