Summary

The IPv6 announcements are one aggregate plus a ladder of nine more-specific blocks, each twice the size of the last.
What it's used for
- A provider. Fifteen IPv4 prefixes and seventeen IPv6 prefixes announced from Bulgaria, five thousand six hundred and thirty-two addresses, across seven observed BGP neighbours.
Notable
- The IPv6 side announces one large aggregate and then a series of blocks carved from inside it, each step doubling in size, so the same space is covered several times over at different granularities.
- The IPv4 side is the opposite shape: fifteen small blocks scattered through one range, most of them the smallest routable size, with more prefixes than the address count really needs.
- Most netnames use a country code, brand and date, with dates clustered in the last days of the year two thousand and a few later additions. One block drops the template and lists only the abuse department.
- That abuse contact is named with the company's website address including the national suffix.
- Four of eighteen queried addresses answered. One is a mail exchanger on the company domain; three give the word for unknown on a domain belonging to a dedicated server brand.
Interesting
- Announcing an aggregate and its pieces at once is usually about traffic engineering: the small blocks steer particular customers down particular paths while the big one keeps everything reachable if the rest are filtered.

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: 432 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.
