The Backbone of .UA Domains
In the vast landscape of domain registries, few names are as straightforward and essential as whois.ua. Registered back on June 26, 2007, this domain has quietly served as the official WHOIS lookup service for Ukraine's national top-level domain (.UA) for almost 19 years. Operated by Hostmaster Ltd, the central registry for .UA domains, whois.ua is the go-to spot for anyone needing to dig into registration details, DNS records, and more for Ukrainian websites.
Hostmaster Ltd, based in Kyiv with a simple P.O. Box 23 address, holds the reins. Contactable via info@hostmaster.ua or +380.44.594.1794, the company is no stranger to the domain world—it's the accredited registry managing the .UA namespace. Their trademark, certificate #65382 registered on August 15, 2006, remains active until October 21, 2035, underscoring their long-term commitment.
What Does whois.ua Offer?
Visiting whois.ua today reveals a robust platform tailored for transparency. Users can perform instant WHOIS queries on .UA domains, pulling up registrant info, creation dates, expiration statuses, and status flags like 'ok' or 'clientHold'. Beyond basics, it displays full DNS records—including A, AAAA, NS, MX, TXT, and even DNSSEC signatures. The site supports both IPv4 and IPv6 lookups, with multiple A records (like 185.159.140.98 and 109.70.105.113) ensuring high availability through load balancing across Hostmaster's infrastructure.
All servers are hosted in Ukraine, primarily under AS29067 (LLC Hostmaster) and AS24725, with Kyiv time zone (Europe/Kyiv). DNSSEC is enabled and signed, a critical feature for verifying authenticity in an era of rising cyber threats. Recent DNS data shows round-robin A records for redundancy: 109.70.108.4, 193.29.220.29, and others, paired with AAAA records like 2001:4130:ce::24.
Technical Deep Dive and Reliability
The domain's nameservers—bg.ns.ua, ho1.ns.hostmaster.ua, and ns1.ns.ua—point to a tightly knit ecosystem. Registrar ua.hostmaster (that's Hostmaster's own service) last updated the record on March 29, 2022, with WHOIS refreshed as recently as April 16, 2026—just a day before this article. Expiration looms on June 25, 2026, giving it about 69 days from now, but given Hostmaster's track record, renewal seems a safe bet.
What's intriguing is the irony: whois.ua is the WHOIS server (whois.ua itself), creating a self-referential loop that's equal parts clever and essential. No major outages or scandals here; it's a workhorse, handling queries for Ukraine's digital economy amid geopolitical turbulence.
Recent Updates and Facts
As of April 17, 2026, the site remains fully operational, with no disruptive changes noted. Hostmaster continues emphasizing security—DNSSEC signing is a standout, protecting against DNS spoofing. The multiple IP addresses suggest a battle-tested setup for handling peak loads, vital for a national registry serving businesses, NGOs, and individuals alike.
Hostmaster's broader role extends to hostmaster.ua, where they offer domain registration, management, and policy enforcement for .UA. No flashy marketing, just reliable infrastructure powering Ukraine's online presence.
In a world of flashy .coms, whois.ua proves that utility trumps hype. It's the unsung hero ensuring you know who's who in Ukraine's web space.
