this comments hit up a good point,
the lower in the OSI stack you go, the harder it is to initiate change.
There is still some (mostly industrial) hardware that has lackluster TCP/IP support at best (for instance, assuming the netmask is always a /24...).
migrating these networks to ipv6 is not possible, and doing 6to4 adds a crapton of complexity.
- azernik 5y agoIt's not about "lower". We can, and do, make massive , non-backwards-compatible changes in layers 1 and 2 every few years and no one is the wiser. Layer 3 is special. It makes that flexibility in all the other layers possible, but keeps none for itself.
- kazen44 5y agomind you though, that layer 3 and 4 are somewhat interlinked.
