- — Why we do not provide daily updates for .io zone?
- — Country-code registars never open their zone files to the public. The only way to discover domains in country-code zones is to do a massive recursive scan of all known websites. That's what we're doing. We use a massive cluster of servers and crawl the Web, then we check and clean the resulting lists. We know of millions of CCTLD-domains in hundreds of zones (and currently know of 216,784 domains in .io zone), but we do not cover 100% of them (some of the smaller websites simply do not have any inbound links and that means that our crawlers cannot find them). Meanwhile we regularly add new domains to this list (1 time / 2 months).
