How does IPv6 addressing work?
Short version: 2000::/3 The currently active global unicast pool RIRx::/12 IANA (by default) assigns /12s to RIRs RIRx:ISPx::/32 RIRs (by default) assign /32s to ISPs RIRx:ISPx:ORGx::/48 ISPs (by default) assign /48s to enterprises (/56s to homes) RIRx:ISPx:ORGx:VLAN::/64 Enterprises 'subnet' their allocation into /64s (debate over [/126 | /127] to P2P links)
I know it's been hashed and rehashed but several orgs I am associated with are about to ask for their allocations from ARIN and we are all realizing we don't really know how the network / subnet structure trickles down from the edge to the host. We really don't have a firm grasp of all of this as there seems to be multiple options regarding how many addresses should be assigned to a host, if the MAC address should be included in the address or if that is just for auto-configuration purposes or what the heck the deal is. There are a lot of clear statements out there and a lot that are clear as mud. Unfortunately, even when trying to analyze which RFC superseded another. Can I just subnet it
all like IPv4 but with room to grow or is each host really going to need its own /84 or something? I can't see why hosts would need any more addresses
Use the IETF/RFC web interface, clearly shows what RFCs where deprecated by, or deprecate/update, a given doc: e.g. - http://tools.ietf.org/html/rfc2461 ... has an obsoleted by, updated by, and obsoletes ... than
today but maybe I'm missing something because a lot of addressing models sure allow for a huge number of unique addresses per host.
My buddy and I are about to go to Barnes and Noble, not having and luck with standard internet media but then we realized... how will we know if any of that is really what we are looking for either?
Depends what you are looking for, and possibly your HW vendor of choice. <<SNIP>>
