ipq.co: create dns records instantly

ipq.co is a new service I put together to lower the barrier for dns management. It’s the tinyurl of the dns world – provide an IP address and you get a random dns record for it (or you can choose your own, if it’s available).  Looking at other dns management systems, I was surprised this hadn’t been done before (and by how awful most of the dns interfaces are out there!)

I wrote it in Ruby using the Rails 3 framework, with the dns records being served by the PowerDNS MySQL back end (though I’ll likely be switching it to use a custom back end using my powerdns_pipe library for more flexibility).

We’re building a big new cloud system over at Brightbox and we’ve been thinking how to provide convenient dns records for our customers.  We already have some basic integration but the resulting records are quite a mouthful. ipq.co is just a bit of an experiment to explore other ways of solving the problem.  There has already been some discussion over on Hacker News about possible applications (and implications) of the service – I’m interesting in how people will use it.

I’ve got some plans for other features which I’ll be adding over the next few weeks, and then I’ll be selling it to Google for low 7 figures, so watch this space.

Wildcard IP lookups

You can now do wildcard IP lookups, as provided by the xip.io service, useful for development environments:

$ host whatever.

whatever. is an alias for 2rvxtx.ip.ipq.co.

2rvxtx.ip.ipq.co has address

New additional domain name

A donor has transferred ownership of a new domain for use with ipq.co.  So now, rather childishly, you can create instant dns records as subdomains of mypen.is:

$ host localhost.mypen.is
localhost.mypen.is has address

Wikileaks Censored by US Judge

A controversial website that allows whistle-blowers to anonymously post government and corporate documents has been taken offline in the US.

BBC News

WikiLeaks and its domain registrar for the wikileaks.org domain name, Dynadot, have been sued by the Swiss Bank Julius Baer, because of leaks claiming illegal activities at the bank’s Cayman Island branch.

The Judge order the DNS registrar to freeze the domain. The main servers are in Sweden though, so the cover names still work (such as the UK one: http://wikileaks.org.uk). There are also mirror sites. This is a good example of why you shouldn’t rely on US domain names (and why we need more diversity of root server control no doubt). Not sure how much better the UK system is though.

The Tor network has hidden services for this kind of thing and though not perfect, helps protect against this kind of attack (the Tor website is censored by my Vodafone ISP btw). A good time as any to volunteer to host a Tor router server.

Cryptome has a Wikileak archive and more information.
