whois.arin.net:43 is for assignment/allocation information. Does not use RPSL.

rr.arin.net:43 is a routing registry that uses RPSL.

My general advice for anybody who cares to listen is to use the RIPE db for your objects if you are based in the ARIN region. It saves time if/when you come to peer with an organisation based in the RIPE region, and it makes your objects easy to find for anybody who wants to look for them.

You can install a route in the RIPE db corresponding to number resources assigned elsewhere by authenticating against the RIPE-NCC-RPSL-MNT maintainer object, for which the plain-text password is "RPSL". Since your new route object will specify mnt-by MAINT-YOURS you will also need to authenticate against that (my favourite method is PGP).
