The future called and it wants more IPv4 space. As much as I am a staunch proponent of IPv6, I get the need for more IPv4. Cloud providers, enterprises, ISPs, they all need it to stave off the CG-NAT as long as possible. Well, some friends came up with a pretty straightforward way to get it - or, according to some “completely break the internet”. We recorded this episode with Dave Taht (who you may remember from our podcast on bufferbloat) and Seth David Schoen about some new drafts they wrote for the Unicast Use of the Formerly Reserved 240⁄4, 127.0.0.0 (loopback space), the 0.0.0.0 block, and the 255.255.255 block, back in February. Needless to say, it was pretty interesting. Full of very polarizing topics (for oh-so-many reasons) this winding and wandering podcast lays out the history as well as the justifications for taking such address blocks - historically held as “untouchable” - and advocates for moving them into general use. Take a listen here and decide for yourself!
