Dong Zhang 写道: thanks for the comments. (1) we will try to unify the terminology in the framework document based on the comments from the community. (2) in the current draft, we are saying Internet operator's language, so a prefix is a collection of the IP address defined by network id and prefix length. for example 166.111.0.0/16 is a prefix and it is a class B address in IPv4. regards, xing > 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?
