Summary
Bifrost Systems
isp business estonia
The AS handle BIFROST-SYSTEMS is held by Bifrost Systems OU.
What it's used for
- The address space carries mixed registrants, with netnames such as
EE-BIFROST-20190605andUS-MISAKA-INC-20170620indicating both Bifrost Systems and Misaka Network holdings. - With 8704 IPv4 addresses announced across 30 prefixes and only 6 observed neighbours, the ratio suggests an access or business network rather than a transit provider.
- Traffic from this AS consists of business and enterprise endpoints, given the operator's classification as a computer consultation and IT services firm in Estonia.
Notable
- Registrants include Bifrost Systems OU and Misaka Network, Inc., with the latter holding specific prefixes like
185.209.86.0/23and188.244.96.0/23. - The address inventory is finely subdivided into numerous /24 and /23 blocks, consistent with an internal corporate estate or managed service provider environment.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
