Since Samsung is a *South* Korean company why would it be blocked? I
have no problem getting it's MX record and the IP address associated
with it. Why would your company block those addresses? Do they not want
to conduct business? Note that whois does NOT use root servers or
anything else. It's a self-contained system and is only used by the
registries.
