Got this a while ago but haven't had a chance to compose a reply. Needless to say, I don't have the sort of time that would be required to assist someone in designing the IP addressing for all of China. If anyone else wants to take a crack, feel free... --Vince --------------- Received: from Argus.Stanford.EDU (Argus.Stanford.EDU [36.56.0.151]) by Valinor.Stanford.EDU (8.6.8/8.6.6) with ESMTP id SAA29665 for <vaf@valinor.Stanford.EDU>; Sun, 21 Aug 1994 18:54:21 -0700 Received: from beijing2.cernet.edu.cn ([166.111.250.2]) by Argus.Stanford.EDU (8.6.8/8.6.6) with SMTP id SAA29664 for <vaf@stanford.edu>; Sun, 21 Aug 1994 18:51:42 -0700 Received: by beijing2.cernet.edu.cn (4.1/SMI-4.1) id AA00261; Mon, 22 Aug 94 09:50:41 CDT Date: Mon, 22 Aug 94 09:50:41 CDT From: yang@cernet.edu.cn (Yang Jia Hai) Message-Id: <9408220050.AA00261@beijing2.cernet.edu.cn> To: vaf@stanford.edu Subject: please help Dear Mr. Fuller, I'm Yang Jiahai, Dept. of Computer Science Tsinghua University. Now, you know, we are planning and designing the CERNET(China Educational and Research NETwork). So we appreciate all sorts of information about Internet and its Protocols, such as IP routing, IP addressing, addresses allocation, etc. We, of course, can get some of the materials through Internet. But, we think these materials are relatively older, and ,you know, the change of Internet is so dynamic. So, I have to turn to you. I read some RFCs co-writen by you, such as RFC1518/1519/1338, et al. Now the urgent thing is that we need know how many numbers of class A, class B and class C are assigned, and how many of them is still un-assigned up to now(Aug 1994 or at least Jan 1994). the second problem is, with CIDR, what routing protocols(including inter-domain routing protocol and intra-domain routing protocol) can work. It's said that BGP-V4 and OSPF will work respectively. But I need some analyzing materials(not just their protocol standard docs., for example, RFC1654 OR RFC1583) which describe them meeting the requirements by CIDR. the third problem is that, now, the Internet Registry(IR) has adopted the IP address allocation plan with CIDR, I do need to know how can we manage our IP address space within CERNET when there are multi-connections from CERNET to ourside(maybe Internet backbone). I wonder whether it is the just multi-homed problem. Maybe you can give me some ideas or help me to search some materials. Please help us, we and all Chinese will thank you.
