AS6723 UA-XAIM
Unclassified RIPE NSP
Summary
SKIF ISP
isp enterprise legacy
A Kyiv fibre ISP that sells to businesses, trading as SKIF. Its legal entity is literally named after the autonomous system — the RIPE registrant reads "AS6723" LIMITED LIABILITY COMPANY — and its routers carry both as6723.net and skif.com.ua reverse DNS.
What it's used for
- Corporate connectivity over fibre across Kyiv and its suburbs, with the operator's own coverage concentrated in office and business centres.
- Handing IP space and BGP sessions to customers who do not have their own address ranges or AS number, which is why customer-facing pools appear directly under this AS.
Notable
- This is a B2B access network, not a consumer broadband provider. The operator's own marketing and its inventory agree on that, which is not always the case.
- It connects to Ukraine's main exchange points, so it is well-meshed domestically rather than dependent on a single upstream.
Interesting
- The registry handle is
UA-XAIMand the maintainer isXAIM-MNT, neither of which has anything to do with the SKIF brand. These are fossils from an earlier holder of the number, left in place through the change of hands — a good reminder that a RIPE handle records history, not the current operator.

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 1,772 prefixes, as published 2026-10-15. 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.
