Name.com hijacks non-existent subdomains and redirects to their servers
My workaround for this was to add a TXT record for *.mydomain.com that just returns a string like "Unused".  This seems to stop them from hijacking any subdomains, and it's not an A record so undefined subdomain names do not resolve, just like if you had not defined them in the first place.<p>(Workaround shouldn't be necessary of course, but this kind of bullshit is par for the course with cheap hosting companies.)
