Summary
Nash Prostir
isp residential ukraine access
NASHPROSTIR-LLC is operated by Nash Prostir LLC.
What it's used for
- The address space carries residential and static client traffic, evidenced by reverse DNS entries such as
b06f2280.clients.nashprostir.comand64-static.nashprostir.com. - The network announces 1024 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with only 2 observed routing neighbours, indicating a local access provider rather than a transit hub.
- Traffic consists of subscriber eyeballs and static endpoints for a regional Ukrainian internet service provider.
Notable
- All registrants for the announced prefixes are listed as Nash Prostir LLC, matching the AS holder.
- The inventory is small and geographically concentrated in Ukraine, consistent with a regional ISP serving specific localities like Zdolbuniv.

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 1,779 prefixes, as published 2026-10-22. 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.
