Ricardo,

What you said is just the first approach I mentioned in the previous mail as
follows:
The first approach is to split the GIRO address into two parts: id and
locator. In this approach, IPv4 address part in GIRO address is used as id,
which means there is no need to change the hosts however it doesn't address
the IPv4 address depletion issue and it introduces a new locator space
compared to LISP/eFIT.

What's the benefit of introducing a new locator namespace compared with
LISP/eFIT which reuses IP address as locator?  Once the id/loc split idea is
introduced, the locator can be allocated in a hierarchical way even though
we still use IPv4/v6 as locator. 

Best wishes,
Xiaohu XU
