Hey guys,<p>I'm looking for a portal where I can hold our internal domains as well as the domains of our clients. The service would need to have a decent DNS system in place, and allow easy management of domains renewals, etc.<p>Specifically (and here's the tricky bit) we'd like to be able to 'group' our domains by client, possibly allowing for separate invoicing or payment details, but not a necessity.<p>Does anyone have any suggestions?<p>Thanks!
