A few years ago we built a tiny web tool to view a site's DNS records. I still use it on a regular basis when I need to do a quick lookup.

Some cool tidbits:

Visit dnsrecords.io/{domain} to jump straight to the results (great for a Raycast/Alfred workflow!)
Type ip or visit dnsrecords.io/ip to display your current IP address
When you share a link to dnsrecords.io/{domain}, it will display the records in the meta & open graph descriptions
