Hi, ripe-list :)

I've been asked (by a telecoms company) to research the options related
to managing IP blocks and integrating with RIPE. Part of this is to see
if there is some existing software out there that can be put to use. So
my question is:

Does anyone know of any good existing solutions for IP Address
Management that integrates with RIPE out of the box or that can easily
be adapted to do so?

The only IPAM solution I have found so far that states integration with
"Internet Registries" is BT Diamond IP's IPControl. If someone has any
experiences with that piece of software, I'd also love to hear about it.
