Adventures in Internet Pollution

One of my coworkers noticed a large and sudden increase in unallocated bogons on the Internet. This normally indicates a new set of IP allocations have been advertised in BGP before the regional registries have had time to update, and, indeed, such was the case here. However, something was different--immensely different: among the blocks being advertised was 191.0.0.0/8, LACNIC's last IPv4 block.
