You mean hosts that violate the DNS RFCS?
In 95 or so, apple came out with (OS) system 7 (AFAIR).
It's DNS implementation strictly complies with the RFCs.
It didn't support _ in hostnames.
This, of course, caused the Apples to not be able to get
to various Notes servers named ny_foo_bar.sub.example.com.
Names which we told them were BAD names (ny was the subdomain,
so have it in the host) and ILLEGAL names.
So we got to go through with a little sed/awk and rename
everything right with a CNAME.
I'm surprised the blogspot.com's DNS servers don't emit an error.
