WHOIS domain name registration information question

Newbie question here. If I were to sign up for a new domain name, would the
sign up information I provide be seen on the WHOIS page? Or is it the
information I give to my web hosting service that goes on WHOIS? (that is,
if it is different of course) Also, we can change this info except for
first/last name at any time right? Is it possible to use a company name or
fake name? I don't want to use my real name.

 

Yes and no.
Personal sign up info such as credit cards etc are private between you and
the host you pay.
There are 3 things that show in a WHOIS, Registrant (you), Administrative
(you again), and Technical (your host)
After signing up, just remember; A computer is only as smart as you tell it
to be and believes the changes you give it in those 3 catagories.
IE: your home address could be 1 Happy Lane and phone # could be 000 111
1111 and that's what will show in a WHOIS lookup.
It's cheaper than paying your host to hide it.

 

That's an "it depends" question. You're going to have to do some
research. For example, some registrars charge an extra fee for added
privacy. Some will gladly sell your email address to anybody with a few
bucks.

No, not in theory, the registrar generally controls what you see in most
"whois" lookups.
