Domain Search Examples · Example 19 of 25 in Filters › DNS

CNAME Pointing to GitHub Pages

POSThttps://api.deepinfo.com/v1/discovery/domain-search

Field: dns.cname.values
Operator: wildcard

Matches records whose dns.cname.values matches the pattern *.github.io. (* stands for any characters).

Hosts whose CNAME points to a GitHub Pages site (<account>.github.io). CNAME targets are stored as fully qualified names, with the final dot, so the pattern ends with ..

In the response, look at results[].dns.cname.values.
