Surprised ICANN doc doesn't cover intranet name collisions issues http://archive.icann.org/en/topics/dns-stability-draft-paper-06feb08.pdf  Does consider file ext collisions: no problem... https://twitter.com/kpyke/status/789156391726387200

To setup my home Windows dev box to be accessible from outside I followed two main steps:
Last time I had to do this there was a service named dynamicdns.org which seems to still exist but no longer appears to be free. Instead I used dnsdynamic.org which is free and has a web API as well as links to and instructions for setting up native tools to dynamically update my IP address.

DSL modem hack used to infect millions with banking fraud malware | Ars Technica

2012 Oct 1, 6:33

According to the links within this article, although the root URI of the router requires authentication, the /password.cgi URI doesn’t and the resulting returned HTML contains (but does not display) the plaintext of the password, as well as an HTML FORM to modify the password that is exploitable by CSRF.

The attack… infected more than 4.5 million DSL modems… The CSRF (cross-site request forgery) vulnerability allowed attackers to use a simple script to steal passwords required to remotely log in to and control the devices. The attackers then configured the modems to use malicious domain name system servers that caused users trying to visit popular websites to instead connect to booby-trapped imposter sites.

Scorching legal response from Dajaz1.com to the unsealed US gov't docs on the illegal, sleazy seizure of its domain name

2012 May 7, 1:25

Its all quite shocking.

Fourth , when I explained that the blog publisher had received music from the industry itself, a government attorney replied that authorization was an “affirmative defense” that need not be taken into account by the government in carrying out the seizure. That was stunning.

draft-liman-tld-names-06 - Top Level Domain Name Specification

2011 Dec 4, 3:00

“The syntax for allowed Top-Level Domain (TLD) labels in the Domain Name System (DNS) is not clearly applicable to the encoding of Internationalised Domain Names (IDNs) as TLDs. This document provides a concise specification of TLD label syntax based on existing syntax documentation, extended minimally to accommodate IDNs.” Still irritated about arbitrary TLDs.

Comcast DNSSEC Trial FAQs

2010 Feb 25, 4:10Comcast is running an opt-in DNSSEC trial for all Comcast customers. Their FAQ covers the incompat. of DNSSEC with their Comcast Domain Helper (typo DNS redirects to Comcast ads... bleh!): "What happens to Comcast Domain Helper, which offers DNS redirect services, when you fully implement DNSSEC? We believe that the web error redirection function of Comcast Domain Helper is technically incompatible with DNSSEC. Comcast has always known this and plans to turn off such redirection when DNSSEC is fully implemented." Yay!PermalinkCommentsdns dnssec comcast faq internet ip security technical

WPAD Server Fiddler Extension

2010 Jan 5, 7:42

I've made a WPAD server Fiddler extension and in a fit of creativity I've named it: WPAD Server Fiddler Extension.

Of course you know about Fiddler, Eric's awesome HTTP debugger tool, the HTTP proxy that lets you inspect, visualize and modify the HTTP traffic that flows through it. And on the subject you've probably definitely heard of WPAD, the Web Proxy Auto Discovery protocol that allows web browsers like IE to use DHCP or DNS to automatically discover HTTP proxies on their network. While working on a particularly nasty WPAD bug towards the end of IE8 I really wished I had a way to see the WPAD requests and responses and modify PAC responses in Fiddler. Well the wishes of me of the past are now fulfilled by present day me as this Fiddler extension will respond to WPAD DHCP requests telling those clients (by default) that Fiddler is their proxy.

When I started working on this project I didn't really understand how DHCP worked especially with respect to WPAD. I won't bore you with my misconceptions: it works by having your one DHCP server on your network respond to regular DHCP requests as well as WPAD DHCP requests. And Windows I've found runs a DHCP client service (you can start/stop it via Start|Run|'services.msc', scroll to DHCP Client or via the command line with "net start/stop 'DHCP Client'") that caches DHCP server responses making it just slightly more difficult to test and debug my extension. If a Windows app uses the DHCP client APIs to ask for the WPAD option, this service will send out a DHCP request and take the first DHCP server response it gets. That means that if you're on a network with a DHCP server, my extension will be racing to respond to the client. If the DHCP server wins then the client ignores the WPAD response from my extension.

Various documents and tools I found useful while working on this:

2009 Dec 3, 4:52Having replaced HTTP with SPDY, Google digs deeper into the Web stack providing their own DNS servers. Also, as Waxy noted, you can't argue with the most memorable IP addresses I've seen: "Configure your network settings to use the IP addresses 8.8.8.8 and 8.8.4.4 as your DNS servers". Also check out their DNS server's DNS prefetching in the performance notes.PermalinkCommentsgoogle dns internet network security performance dns-prefetching technical

Bits Up!: DNS Prefetching for Firefox

2009 Jun 22, 3:28Details on Firefox's DNS prefetching: "The Firefox implementation takes this approach one step further than just pre-resolving anchor href hostnames. It uses the prefetch logic on URLs that are being included in the current document. By this I mean that it uses the prefetch logic on things like images, css, and jscript that are being loaded right away, in addition to anchor links which might be clicked on at a slightly later time."PermalinkCommentsdns dns-prefetching html performance networking firefox mozilla technical
