it's better to use 'host' or 'dig' rather than nslookup.
there is nothing special about 'www' - it's a convention, but it's a
subdomain just like anything else.

so if you want www.yourdomain.com to resolve (btw, it's generally a good
idea to give your real domain name rather than a fake one like
'mydomain.com', which i'm assuming you don't own), you will need to
creat a subdomain 'www', and add an A or CNAME record for this
subdomain.

the two common ways of doing this are:

@	IN A 123.123.123.123
www	IN A 123.123.123.123

or
@	IN A 123.123.123.123
www	IN CNAME mydomain.com.
(or more succinctly)
www	IN CNAME @
