IPv6 is an update to IPv4. The most notable change is that the address space is expanded (from 32 bits to 128 bits).

IPv6 from an application perspectiveEdit

Support for IPv6 is currently being added to LwIP. Up to version 1.4.x LwIP can use either IPv4 or IPv6, but not both. Code for dual Stack operation is in the current development version (which can be downloaded from git). It will probably be released as version 1.5.0 [1]. Some consider LwIP IPv6 quite stable [2].

The development version can be downloaded from git:
