This is one of the areas where I think the results will live up to, and even exceed, the hype and expectations. This was a pretty good read, with a combination of real world examples and some forward looking expectations that seem to be more than pie in the sky.

DNS questions for Cisco IOS DNS server

Filed under: Cisco,Internet — Landis V @ 11:28 pm

Caching: Does the IOS DNS server cache TXT and SRV records? How about negative caching (DNS NCACHE, RFC2308)?
- ANSWER (partial): Yes, it appears that at the very least it supports caching of TXT and SRV records.
Which provides better DNS behavior for clients – assigning a search list to the client, or having the router act as a forwarder and check the search domains itself? Pros and cons for each?
- ANSWER (partial): It doesn’t appear that IOS actually postpends the search suffixes for some reason. Eventually I will go back and attempt to address this; at the moment I suspect it’s my configuration rather than a Cisco bug, but as easy as it seems to be to hit bugs in IOS code anymore, I won’t completely rule that out.

Proposed changes to WHOIS system called ‘extremely disquieting’ – Network World

I can see both sides of this. I think there is significant benefit to having the name and contact information associated with the domain record. I think it promotes a certain amount of responsibility. However, I have also had instances where it would be nice to privatize or restrict the visibility that information, and I have at times taken advantage of registrar privacy features.

Your own Dynamic DNS in 3 steps | The Nexus

Interesting idea, perhaps provides a little bit of added flexibility (and reduced cost) compared to Dyn, though I don’t have any complaints about Dyn at this point. Also review the DDNS and TSIG articles on Wikipedia as well as RFC2136. Still thinking that perhaps a hybrid HTTPS method; would allow any web server one had available to potentially be able to serve as a receiver for the updates as long as it had at least enough outbound access to give the information to the BIND server, allowing for possibly a bit more obscurity in the update path; also wouldn’t require that whatever host received the update information not have BIND running (i.e., perhaps a web host) as long as it could establish an outbound communication to the BIND server – or write to some file that the BIND server could retrieve.

Interesting question therefrom – short of a VPS, is it possible to use client-side certificates to identify a client to a webserver? How about self-signed client certificates?
