Has anyone looked into what some use cases are for using a FQDN as a prefix
in a hostname? (Or even how common such names in use are?) I could imagine
setting up a proxy or archival service with such a scheme:
www.google.com.corp.com/search?q=flowers
www.myblog.net.proxy.com?rev=2017-08-09
If a large percentage of hostnames with a FQDN prefix are phishing related
it might be an initial pool for further research by agencies.
