IPv4 literals and IPv6-only hosts
by Cameron Byrne 17 Sep '10

17 Sep '10

In planning for IPv4 exhaust, i have been tinkering with NAT64/DNS64 in preparation to launch it with customers. In my experience it works well, my phone has been Ipv6-only + NAT64 for over 6 months.... no major roadblocks. There have also been other documented NAT64 deployments that work well, especially on mobile devices http://tools.ietf.org/html/draft-arkko-ipv6-only-experience-01 I do not believe that there is much risk in deploying NAT64, the customer experience can be engineered on mobile to be very good, but there is some minor risk that does not need to be there because of content providers using IPv4 literals, which are IPv4 address embedded in content (HTML, XML, apps...). I think across the industry people believe using names (FQDNs) is a better practice than embedding IPv4 addresses, nonetheless it happens. So, in an effort to help content providers understand that IPv6-only customers will not be able to access their IPv4 literal laden content, i have created this group http://groups.google.com/group/ipv4literals The group is not about name and shame or fixing every instance of literals, it is about making sure that the risks of using IPv4 literals are known by the content providers and that they have a good opportunity to fix it, start using FQDNs or deploy IPv6. Also, if anyone has a good nytimes.com or Amazon video on demand contact, you may want to forward this on to them. Thanks, Cameron http://groups.google.com/group/ipv4literals http://groups.google.com/group/tmoipv6beta

Chase.com outage
by N. Yaakov Ziskind 16 Sep '10

16 Sep '10

Does anyone have any information (beyond the wimpy statement that "technical issues" were to blame) on the Chase outage? It seems that when a multibillion dollar company's major web site is down for more than a day, there must be juicy "technical issues" that beg to be told. So, can anyone dish? :-) -- _________________________________________ Nachman Yaakov Ziskind, FSPA, LLM awacs(a)ziskind.us Attorney and Counselor-at-Law http://ziskind.us Economic Group Pension Services http://egps.com Actuaries and Employee Benefit Consultants

RE: XO Routing
by David Hubbard 16 Sep '10

I know their own phone systems went down, or perhaps were overloaded; we lost our office connection to them but our phones remained online. I called their tech line by cell, was told thanks for calling XO, we are experiencing technical difficulties and then it hung up on me. :-) This seems to happen about once a month with them though so I'm used to it.

Reverse DNS for IPv6 client networks
by Elmar K. Bins 16 Sep '10

16 Sep '10

Hi guys, I am looking for operational experience here. We have just turned up IPv6 in our "guest wireless", by way of using RA for address distribution and DHCPv6 for the DNS server address (stupid, yup). Apart from the dhcp6 part seemingly not working on Juniper ISGs (or maybe it's my windows *and* that Ubuntu), I now see IPv6 addresses instead of names. I as a networking droid have not much quarrel with that, but I am interested in how or whether at all others handle this. Are you creating DNS entries somehow (reverse and, ultimately, forward), are you using BIND "generate" statements, are you using wildcards...or are you just ignoring this for the "dynamic boxes"? Please enlighten me! Elmar.

ip block history.
by Greg Whynott 15 Sep '10

15 Sep '10

probably an odd question … we have been assigned a few large blocks of IPs, and while configuring BGP i got to wondering what these block's history might be. who had them in the past, etc.. is there a publicly accessible db or similar which tracks that type of information, or is that liability concern? thanks! greg
