Hey, Do You Guys Have a List of All the Domains in [ccTLD]?

This blog post explains DomainTools’ approach to gauging and improving coverage of domains across ccTLDs and gTLDs, highlighting the difficulty of enumerating active domains due to limited access to ccTLD zone files. It references CENTR’s updated domain counts to benchmark coverage, describes the use of internal/external data and significant computing resources for domain discovery, and notes a snapshot of coverage for the top 25 TLDs while flagging .TK as a special case.
