The Mayan Internet Calendar

I'm getting ready to fly out to Vegas for Cisco Live! 2011. It's looking to be a pretty good show with Cisco confirming nearly 19,000 attendees and another 40,000 virtual participants. Cisco Live has been the leading networking show in the industry at least over the last five years in my opinion. Obviously not everyone uses Cisco, but for networking geeks like me, it's a great venue for discussuing IPAM.

In fact, I will be giving a talk at the Cisco booth on Thursday. Since it's the last day of the show, which is traditionally pretty dead, I thought I'd add some humor and lighten it up a bit for those diehards who stick around for it. The title of my talk is "The Mayan Internet Calendar". I don't know about the end of the world, but we are certainly approaching the end of the Internet world as we know it as a nearly homogeneous IPv4 network.

As the explosive demand for IP addresses continues, soon this demand will be met with IPv6 addresses. As the IPv6 population grows, the complexion of the Internet will change to that of a dual-protocol Internet for quite some time. If you'll be the show, stop by and check it out, or if you're leaving early, stop by the BT Diamond IP booth to say hi.

We'll see if the purported Mayan prediction of the end of the world comes next year, but it's a sure bet that 2012 will bring the end of the Internet as we know it!

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...
