Unclassified RIPE NSP
Summary
Angel Soft
isp hosting business
A halving ladder out of one block, three prefixes sharing one date, and reverse names written backwards.
What it's used for
- A Bulgarian internet provider. 27,136 addresses across ten IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.
Notable
- The largest blocks are
87.252.160.0/19and95.168.224.0/19. - Four prefixes descend from one neighbourhood:
80.80.128.0/20,80.80.144.0/21,80.80.152.0/22and80.80.156.0/23. - Netnames are dated
BG-ANGELSOFT-20010717(three blocks),20050923,20071022and20090107. - Six of eighteen sampled addresses returned names, all of the form
254-183-252-87.filibe.net.
Interesting
- The reverse names run the address backwards.
87.252.183.254answers as254-183-252-87.filibe.net, last octet first. Both orderings are used in the wild, and the choice is made once, in a script, by whoever set the zone up. It never gets revisited. - The
80.80blocks form a ladder: a /20, then a /21 beginning where it ends, then a /22, then a /23. Three of them share a single 2001 date, so this is not gradual growth but one application filled in four separate requests, or one clerk recording four assignments on one afternoon. - One neighbour carrying 27,136 addresses means this network reaches the internet through a single upstream. That is unusually simple for a provider of this size, and also a single point of failure.
filibe.netis the old name for the city of Plovdiv rather than anything resembling the company name. Reverse zones get whatever domain the operator already owned.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 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.
