LOC Record Look Up

The LOC look up checks for a geographic location record, which can publish latitude, longitude, altitude, and precision for a host or domain directly in DNS.

Blacklist Look Up

Looks up whether this domain's IP address (or the IP address you entered) appears on common email blacklists (DNSBL) — being listed can cause outgoing mail to be rejected or sent to spam.

How to use this tool

Pick a lookup type from the dropdown, or type a shortcut straight into the field — e.g. mx:example.com, all:example.com, spf:example.com, whois:example.com — and press Enter.
Enter a domain name (e.g. example.com), or an IP address for PTR and blacklist look ups.
Toggle "Also look up blacklist status" above to include a DNSBL look up alongside your search.
Your last 20 look ups are saved in the History panel so you can revisit them anytime.
