Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
Spamhaus DROP
On Spamhaus ASN-DROP Spamhaus lists this entire
network (associated domain bignet.ua)
as controlled by, or hijacked for, cybercrime. Many operators null-route
everything it originates.
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.
