+1 on search term! And if you enter a domain that doesn't exist, it throws you back to the homepage with no way to fix it :(

Another feature request: When entering an IP, there's very little information available on it (only the hosting provider). Would be nice to get latlong, country etc (a la https://www.iplocation.net/).

Because seriously, that is an insanely cool database. I can even find all the sites that share my domain's Cloudflare IPs.
