IPv6 – /48 allocation in /64 chunks – that’s a lot of addresses 21st January 2011 By Greg Ferro Filed Under: Blog I posted yesterday about changes to RFC3177 for IPv6 allocation.
1.) Each character in an IPv6 address represents 4 bits (a nibble). Since 0xF is 1111 in binary, it's easy to fall back into an IPv4 habit and forget that 0x11 is actually 0001 0001 in binary. 2.) Each IPv6 set represent 16 bits (4 characters at 4 bits each). Keeping this in mind can make breaking up subnets a … IPv6 allocations: The tide comes in | Network World As IPv6 provider-independent allocation policies kick in, it is likely there will be a considerable boom on the enterprise side. All told, 2008 may be the year that IPv6 makes it to prime time. Internet Assigned Numbers Authority (IANA) Policy For
4 IPv6 address allocation hierarchy and techniques. Now that we’ve seen how your IP address plan impacts the manageability of your network and we’ve discussed the goals you should consider when developing your IPv6 address plan, let’s delve into the mechanics of performing IPv6 allocations.
IPv6 Lookup Tool. The IPv6 Info tool provides a complete set of IPv6 address information. The IPv6 Info tool provides WHOIS information, Autonomous System Number (ASN) information, expanded and compressed IP address information, and reverse lookup information for an IPv6 address.
IANA IPv6 Allocations to Date. The official IANA allocation history for IPv6 similar to the one above for IPv4 /8 blocks is here. There have been a number of small allocations in 2001::/16. The allocation that my /48 (2001:470:3d::/48) came from was granted to ARIN on July 1, 1999 (Hurricane Electric was a very early adopter).
IPv6 dynamic prefix? WAT - BT Community I hardly need to point out how useless that is for businesses wishing to set up public servers on IPv6. I suspect (conspiracy theory warning!) that there is a strategy to make companies wanting static IPv6 pay for some vastly expensive additional service. Or maybe in future it … IPv6 and /64 block allocation - Server Fault IPv6 allocations (and assignments) should be done in much larger blocks. In "Internet Registry Speak" an allocation is usually done to an ISP while an assignment is usually done to an end-user. Therefore usually allocations are much larger than assignments, because an ISP needs a big block to make assignments from to its customers. IPv4 and IPv6 Address Spaces - The Third Internet IANA IPv6 Allocations to Date. The official IANA allocation history for IPv6 similar to the one above for IPv4 /8 blocks is here. There have been a number of small allocations in 2001::/16. The allocation that my /48 (2001:470:3d::/48) came from was granted to ARIN … Getting IPv6 private addressing right | APNIC Blog
