Hello All, I am looking for some good reading material to get a better understanding of IPV6. I know how to convert HEX into decimal format. What I am looking for is how to under the CIDR notation and break them out into subnets. Thank you in advance. MAR.

Hi! While not a IPv6 exclusive book, the TCP/IP Guide by Charles M. Kozierok has an overview of most topics related to TCP/IP. It might not be very detailed, but it is usually detailed enough. The book can be found online here http://www.tcpipguide.com/free/index.htm , so as long as you don't mind sitting by the computer and reading, you don't need to buy it. The following section http://www.tcpipguide.com/free/t_InternetProtocolVersion6IPv6IPNextGeneratio... talks about IPv6, and amongst other things the addressing scheme. HTH! -- Niclas

Hello All,
I am looking for some good reading material to get a better understanding of IPV6. I know how to convert HEX into decimal format. What I am looking for is how to under the CIDR notation and break them out into subnets. Thank you in advance.
I recommend 'Running IPv6' by Iljitsch van Beijnum or 'IPv6 Essentials' by Silvia Hagen. Also Chris Grundemann wrote a Day One Guide for Juniper entitled "Exploring IPv6" which you can download for free at http://forums.juniper.net/t5/Day-One-Books/Day-One-Book-Exploring-IPv6/ba-p/ 52402 - Chapter 1 in the Day One guide has a lot of really good information on understanding IPv6 addressing formats, subnetting, etc. Either one of those should be able to answer most of your questions.

If you think in hex its straight forward to do CIDR in IPv6. There are only three groupings on a non nibble boundaries. You also display the entire 128 bits with the least significant bits set to zero. The :: notation is used to shorten the displayed address. e.g for a /57, /58 and /59 with leading bits of 2001:23bc:fe8d:b200::/56 you would have. /57 {0,1,2,3,4,5,6,7} {8,9,a,b,c,d,e,f} 2001:23bc:fe8d:b200::/57 2001:23bc:fe8d:b280::/57 /58 {0,1,2,3} {4,5,6,7} {8,9,a,b} {c,d,e,f} 2001:23bc:fe8d:b200::/58 2001:23bc:fe8d:b240::/58 2001:23bc:fe8d:b280::/58 2001:23bc:fe8d:b2c0::/58 /59 {0,1} {2,3} {4,5} {6,7} {8,9} {a,b} {c,d} {e,f} 2001:23bc:fe8d:b200::/59 2001:23bc:fe8d:b220::/59 2001:23bc:fe8d:b240::/59 2001:23bc:fe8d:b260::/59 2001:23bc:fe8d:b280::/59 2001:23bc:fe8d:b2a0::/59 2001:23bc:fe8d:b2c0::/59 2001:23bc:fe8d:b2e0::/59 Note the last nibble before the :: is 0 and is there so that the final bits are all zeros. The following all represent the same cidr block. 2001:23bc:fe8d:b2e0::/59 2001:23bc:fe8d:b2e0:0000:0000:0000:0000/59 2001:23bc:fe8d:b2e0:0:0:0:0/59 Normally you just assign /64 subnets and delegate address blocks on nibble boundaries to end customers, e.g. /48, /52, /56 or /60. This means that end customers don't need do deal with cidr block if they don't want to. They can just route individual /64.

More ideally, you give every end site a /48 if they want more than one network. Owen On Apr 4, 2011, at 5:59 PM, Mark Andrews wrote:
