This is a chrome extension which inspects and find domains that don't resolve. This is primarily to help detect Second Order Subdomain Takeover. A second order subdomain takeover is when you're able to register a domain (expired, typoed, etc.) which are being referenced by some pages on some other domains. This may allow full or parital control over the page where the resource is being included/referenced.
These are some resources on the very topic:
