Given my recent post on IPv4 exhaustion, I read with interest that 1.0.0.0/8 has been reallocated (to APNIC) as part of the efforts to debogon and reuse address space.
Previously there’s been discussion on which /8 should be allocated. A good read, and covers issues I’d expect to become more important as the IPv4 space is depleted. IANA keep a document on /8 RIR assignments here.
I don’t do much networks stuff nowadays, but what’s important from my programmatic point-of-view is IP address validation within user interfaces – I know at least two systems I’ve been involved in developing have IP address input validation; consequently I think you can probably expect to see older (poorly programmed) routers thinking erroneously ‘oh, that IP address is invalid!’.

The debogon’ing will help, but that just gets rid of the bogus announcements of it, it doesn’t help with all the broken organisations and software which use 1/8 internally.
I pity the small organizations which end up with 1/8 allocations, and especially the technical staff who end up having to explain to their management why they’ve got "bad IPs".
