Hi Xing
I'm quite confused with the terminology when I read the draft.
The draft shows:
IPG4: The global IPv4 addresses
ISP4: The ISP's IPv4 prefix
ISP6: The ISP's IPv6 prefix
IPG4prefix: The IPv6 address representation of IPG4
ISP4prefix: The IPv6 address representation of ISP4.
I have some questions:
1) Is IPG4prefix a prefix or an address? According to the definition, the IPv6 address representation of IPG4, I guess it is an address. But why you include the word "prefix" in it?
2)In figure 4, Represent the IPv6 addresses in IPv4 (stateful)
+--+--+--+--+--+--+--+--+--+--+
ISP6prefix| ISP6 |
+--+--+--+--+--+--+--+--+--+--+
\ /
\ /
Mapping is based on session
initiated states
\ /
\/
-+-+-+
|IPv4|
|pool|
-+-+-+
Now that ISP6 is a prefix, what do you mean here?
I feel that the terminology is not clear. And the naming has no rules. IMHO, it isn't convenient for understanding.
Could you please explain these more clearly?
Thank you very much.
B.R.
