1.0.0.0/8 Reallocated
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!'.

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".
