UOS is operated by Ukrainian Optical Systems and Technologies LLC.
What it's used for
- The address space carries residential and business internet access, evidenced by reverse DNS entries such as
mail.ost.kiev.uaandIP-232-128.br1.uos.net.ua. - The AS announces 2560 IPv4 addresses across 2 prefixes and maintains 7 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
- Traffic consists of subscriber eyeballs for optical fiber connections in Kyiv districts (Holosiivskyi, Chapayka) and surrounding suburbs (Novoselky, Chabany).
Notable
- Registrants for both announced prefixes (
178.214.192.0/21and194.150.232.0/23) align with the announcer, listingUKRANIAN OPTICAL SYSTEMS AND TECHNOLOGIES LLCunder the netnameORG-UOSA4-RIPE. - The inventory is compact, consisting of two contiguous IPv4 blocks with no announced IPv6 prefixes.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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 1,783 prefixes, as published 2026-10-20. 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.
