Ok, to avoid any confusion Jann (chair of the TAC) and I have had a chat about this today. We agreed that it would make sense to reserve a small part of the address space specifically for documentation relating to 44net. I have updated the Portal to reflect this:
44.128.0.0/17 This is reserved for testing. Anyone may use this address space for private testing purposes, it will never be allocated to anyone, it will never be advertised on the Internet at large.
44.128.128.0/17 This is reserved for future testing. It also will never be allocated to anyone, nor will it ever be advertised on the Internet. Within this address space we have allocated:
44.128.252.0/22 This is reserved specifically for documentation.
Anyone implementing filtering may safely route 44.128.0.0/16 to /dev/null
