Hi All

I need to provide a function on my site whereby a user can enter a number of
ip addresses (one per line) so that I can submit this en masse to string
holding space in my db.

My problem is that I want to keep this list sorted as they enter the ip
addresses and I want to check for duplicates so that they don't enter the
same ip addresses twice.

I was going to do this as a simple form submit and add each entry as a
database row so that I could ORDER BY to get the sort and check for
duplicates on the submit, but this client/server submit really slows the
whole process.  It would be great if I could order by and duplicate check on
the client side so that once done all I'm doing is one client/server 'post'
to the db.

Is this feasible?

Thanks
