.co WHOIS lookup

.co is managed by Ministry of Information and Communications Technologies (MinTIC). Its registry has no RDAP service yet, so a lookup here shows the domain's DNS setup, and full details come from its WHOIS server, whois.registry.co, or the registry's website.

What a .co lookup shows

The nameservers and the mail setup read from DNS. Registration details need the registry's own lookup until it offers RDAP.
