Yeah, but IIRC (and I possibly don't) isn't it OK to specify it as 
'customer allocated' for a /29 and longer prefix? Wasn't aware that 
they had to specify for each individual IP. I understand that RIPE can 
be quite anal with paperwork, but surely an exact record of EVERY 
address allocated would be a PITA to manage?

Besides, I think Eclipse are the only people that ask for it...

True, however, I can see John wanting to use the extra IP address at a 
later date (probably not too much later), hence I was specifying a 
solution to fit the customer, not a 'one size fits all' solution :)

Yeah, NAT is a great invention... but I still love my block of IP 
addresses, it's as close to a 'proper' network as I can get without 
having an ASN :(
