— Why we do not provide daily updates for .co 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 298,797 domains in .co 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).

The .co domain is one of the most popular of the two letter domains. It is the internet country code top-level domain for Colombia. It is a relatively new domain that is managed and administered by .CO Internet S.A.S.

At the present there are no restrictions whatsoever when it come to registering a .co domain, meaning any individual or entity can register any second level .co domain.

.CO Internet S.A.S is an organization based in Bogotá, Colombia. It is currently the sole administrator for the .co domain having taken control of the domain in 2009 through a public procurement process. Upon taking control of the management of the domain, .CO Internet S.A.S introduced some policies that saw domain registration become more liberal and transparent. The policies that were introduced were aimed at improving international involvement and business practice through making the .co domain available to any entity even if it is not located in Colombia.

• The first single letter .co domain name was “”.
