Unclassified RIPE
Summary
Zulu Ltd.
isp residential bulgaria access
AS-ZULU-BG is operated by Zulu Ltd., a Bulgarian internet service provider.
What it's used for
- The address space carries residential and access traffic, evidenced by reverse DNS entries like
host-255.net-155.sof.zulu.bgandhost-254.net-157.sof.zulu.bg, which indicate host-based naming conventions typical of consumer connections. - The AS announces 2304 IPv4 addresses across 2 prefixes, while maintaining 59 observed neighbours. This ratio of moderate address space against a high number of peering partners suggests a role focused on providing internet access to end-users rather than pure transit.
Notable
- The registrants for both announced prefixes,
87.239.152.0/21and195.88.141.0/24, are listed as Zulu Ltd. with the netnamesZULU-NETandZULU-NET2respectively, aligning perfectly with the AS holder. - The address inventory consists of one /21 and one /24 block, both located in Bulgaria, indicating a consolidated domestic footprint without significant international or leased space fragmentation.

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.
