Book / Literature Recommendations
Hi All, What is the single best book you have read on networking? That's a wide topic so to clarify I'm talking about service provider networking but I do enjoy all aspects really and don't want to limit my self to one area of networking. I'm often reading technical books about technology X or protocol Y but they are generally explaining a new technology to me, how it works and how to use it (and how to configure it if its a book by a vendor like Juniper or Cisco). That is usually a learning exercise though required for an upcoming project or deliverable. I haven't read many vendor neutral books recently that explained concepts, or technologies, or paradigms that I found profound, radical and extremely useful. I feel like I'm just reading networking books these days to learn a new technology for a period of time (until a project completes) then moving on to the next technology (book). Longevity of the information doesn't seem as profound as it used to; BGP design principals will stay with me for decades until we reach the need for BGP v5 or similar, learning about 8b/10b encoding was interesting but not really required for my line of work more out of hobbyist interest and serves no practical purpose as a network engineer. Cheers, James.

ISO 3166 MA allocates a code, and tries to do that as soon as possible the country has a name etc., hopefully it can be arranged at the date the country became in existing (which was the case with recent new coutries (SS, SX, CW etc.) but that are no guarantees. Then ICANA can pick a registry, delegate etc. Whether they plan to prepare for that in advance one has to ask IANA. jaap

It should be rejected for the same reason that 192.168.10.0/16 is invalid in a prefix list or access list. Any decent router won't allow you to enter just anything in that range into the export rules with a /6, except 2000:: itself, and will even show you a failure response instead of silently ignoring the invalid input, for the very purpose of helping you avoid such errors. 2001::1/6 would be an example of an invalid input -- there are one or more non-zero bits listed outside the prefix, or where bits in the mask are zero. Only 2000:::::::/6properly conforms, not just any IP in that range can have a /6 appended to the end. Which is one of the reasons I think it was more likely a typo for 2000::/3 being entered via numeric keypad. 3 and 6 are adjacent on a numeric keypad and both 2000::/3 and 2000::/6 are valid prefixes.

That's a wide topic so to clarify I'm talking about service provider networking but I do enjoy all aspects really and don't want to limit my self to one area of networking. I'm often reading technical books about technology X or protocol Y but they are generally explaining a new technology to me, how it works and how to use it (and how to configure it if its a book by a vendor like Juniper or Cisco). That is usually a learning exercise though required for an upcoming project or deliverable. I haven't read many vendor neutral books recently that explained concepts, or technologies, or paradigms that I found profound, radical and extremely useful. I feel like I'm just reading networking books these days to learn a new technology for a period of time (until a project completes) then moving on to the next technology (book). Longevity of the information doesn't seem as profound as it used to; BGP design principals will stay with me for decades until we reach the need for BGP v5 or similar, learning about 8b/10b encoding was interesting but not really required for my line of work more out of hobbyist interest and serves no practical purpose as a network engineer. Cheers, James. I recommend reading the NANOG meeting materials archive presos and videos. Good to see what people are actually doing, real lessons learned. CB
