IPv6 Deployment in U.S. Nearly Doubles Since World IPv6 Launch

With all the IPv6 fanfare and press leading up to World IPv6 Launch this past June 6th, after which things quieted down, I've been wondering, has anything happened since? According to ongoing research  conducted by the England Chapter of the Internet Society published on the RIPE NCC website, most countries worldwide have experienced higher IPv6 penetration as measured in August, 2012 vs. June, 2012. In fact, the U.S. experienced the largest percentage increase in IPv6 penetration over the period, leaping from 6.17% to 11.46%!

The research project is dubbed the IPv6 Matrix Project, and full details about the project can be found on its website. In a nutshell, the system attempts an "IPv6 crawl" by looking up DNS records for the top one million websites (and then some) according to Alexa. The system uses DNS results to initiate connection attempts to email, web and time servers.

The IPv6 Matrix website home page displays a world map, which I assume displays the very latest measured penetration percentage as you mouse over each country. Mousing over the U.S. today indicates 22.47%, but this particular metric includes only the .us ccTLD, not .com, .net or .org which are included in the report metrics published on the RIPE website.

Interestingly, results in Asia were surprisingly low given the general lack of IPv4 space coupled with tremendous wireless and broadband growth in the region. Perhaps most Internet hosts are behind NAT64 gateways. While the England chapter of the Internet Society plans expand the data analytics over time, additional "crawlers" distributed across the globe may provide more robust sampling. But certainly this is a great start in terms of publishing one measure of IPv6 deployment.

Handy AAAA filter in BIND 9.8

The ISC introduced a pair of new configuration file options in BIND 9.8 to enable administrators to easily filter who may receive AAAA record type responses even if valid responses exist. For example, clients on subnets that do not have IPv6 network access can be excluded from receiving affirmative answers for AAAA queries. This feature provides simpler administration than the alternative mechanism using views. The first option, filter-aaaa-on-v4,defines whether the server will return AAAA records to certain clients. Such clients are defined by the address match list parameter of the second option, filter-aaaa. Note that BIND must be compiled with the --enable-filter-aaaa option on the configure command line to enable AAAA filtering. The syntax of these options is as follows: filter-aaaa-on-v4 (yes | no | break-dnssec) ; filter-aaaa {addr_match_list;} ; The filter-aaaa option identifies the address match list for which the filter-aaaa-on-v4 option is to be applied as described

Inglorious DDI

We all know how critical DHCP/DNS/IPAM (DDI) services are. Your network cannot function without them. But like most foundational elements of anything, they are certainly not glamorous...like good luck finding a home designer who specializes in home foundations. I would not be shocked should HGTV pass on my brilliant concept for a foundation building show. I suppose most people would find a show detailing footing depths and concrete pouring techniques rather boring.  Nevertheless, there are countless shows for redesigning and remodeling homes. On most episodes the foundation is out of sight, out of mind. If it's stable, no one wants to pay it attention, they just expect it to keep doing its job, supporting the structure. Once in a while a foundational issue is brought up that unexpectedly threatens to raise the budget to heighten the drama. All work stops until the issue is addressed. And you'll notice that the owner never denies paying the extra amount to fix the issue.

BIND 9.8.0 Adds DNS64 Support - Part 2 - How is it configured?

BIND 9.8.0 introduced a new dns64 option statement that can be configured within the server named.conf options block or within a view options block. Recall from a prior post that DNS64 configures a recursive DNS server to issue A record queries on behalf of a client requesting AAAA records, then appends the returned IPv4 address to a defined IPv6 prefix. This manufactured IPv6 address enables the querying host to connect to a NAT64 gateway which will terminate the IPv6 connection from the client and map it to an outbound IPv4 connection to the appended IPv4 address, completing the connection! Whew! BIND offers a number of useful parameters within the dns64 statement to control this process. The statement syntax is: dns64 IPv6_prefix { [clients {address_match_list };] [mapped {address_match_list };] [exclude {address_match_list };] [suffix IPv6_addr;] [recursive-only (yes|no);] [break-dnssec (yes|no);] }; The IPv6_prefix parameter is the prefix to which returned
