With bash / ksh / zsh aliases you can't rearrange the parameters, but
you can always add them to the end.  E.g. this:

 alias .arin='whois -h whois.arin.net n +'

can be called as

 .arin 64.64.64.64

and will expand the way you want.  However, if you needed to have
something come after 64.64.64.64, or to be mixed in with the whois
options, you'd have to use a script or a shell function.  I.e., if you
wanted to pass the name of the whois server rather than hardcode it:

  .arin() { whois -h $1 n + $2; }

That can't be done with an alias (except in csh).
