Unclassified RIPE
Summary
O2 Business Services
business isp slovakia o2
The AS handle O2BS is held by O2 Business Services, a.s.
What it's used for
- The address space carries business and enterprise connectivity, evidenced by netnames such as
SK-BS-20061017andSK-O2-STATIC-POOL-20180523-02, and reverse DNS entries pointing too2inet.sk. - With 43,264 IPv4 addresses announced across 9 prefixes and 44 observed neighbours, the ratio suggests a regional access or business ISP role rather than a pure transit provider.
Notable
- Registrants are consistent with the announcer, primarily listing O2 Slovakia, s.r.o. and O2 Business Services, a.s.
- The address inventory is subdivided into multiple /19, /20, /22, and /24 blocks, indicating a structured corporate estate with site-by-site segmentation.

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.
