Summary

Netguard

Bulgaria · AI-generated

residential fiber bulgaria access

The AS handle NSS is held by Netguard LLC.

What it's used for

  • The address space carries residential fiber-to-the-home traffic, evidenced by the reverse DNS record ftth-214-254.Krichim.Fiber-Home.net.
  • The network announces 1024 IPv4 addresses across 1 prefix (185.111.212.0/22) and maintains 1 observed neighbour, a ratio indicative of an access or eyeball network rather than a transit provider.

Notable

  • The RDAP registrant NETGUARD LLC aligns with the registry holder NSS NETGUARD LLC and the PeeringDB identity NETGUARD.
  • The inventory consists of a single contiguous /22 block located in Bulgaria, with no IPv6 prefixes currently announced.

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 1,771 prefixes, as published 2026-10-15. 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.
