Earlier quoted context omitted.

It's up to the web site owner to check HTTP Host. You could equally have registered hakernews.com and CNAME'd it

I agree, web site owners should be checking the host. Most of them don't. And yes I could easily create a CNAME record to do the same thing but you have to have a reasonable amount of knowledge to do so. Unlike this tool.

It's not even necessary to check the HOST header. Simply use name-based virtual hosts and forbid access to the default virtual host. This denies access to simple drive-by bots that crawl IP ranges and others that request a HOST that isn't configured as a virtual host.

Perhaps I'm missing something, but what exactly is appealing about this service and/or is new and innovative? It's trivial enough to put a web interface in front of BIND or djbdns to replicate this behavior to where I'm trying to understand why this got ranked highly? I am by no means bashing the creator of this service nor the service itself - I'd just like to understand what additional value is being provided here…

You boot up an ec2 instance and want to give a domain name to a friend that isn't 100 characters long. How much effort does it take you setup your bind solution? Particularly if you've never setup dns before. Can I do this given that I'm not running any other servers? The popularity of dyndns should give you a sense of demand.

I've been using DNS, DNS Services, DNS Administration Services and DNS Configuration Tools for 12 years.

This is the first time I've ever seen a tool/web page that has done this so simply.

It may be trivial, but I don't think I've ever seen anyone do it before.

Oh, and the hacker value is very clear - if you notice there is (soon) going to be an update that will let you also update your DNS record.

It's clean, quick, and simple. Add the ability to submit updates via email, and you have a "posterous for DNS updates." :-)

I am not sure how I feel about this. A domain name implies ownership of the site. It's kind of like reverse domain hijacking. See, http://hackernews.ipq.co/ Am I missing something?

I don't think it implies ownership, but it could certainly mislead users who are not familiar with the purpose of DNS. It's always been trivial to point one of your own domain names at someone else's IP address (or create a CNAME), but this hasn't been the source of any major abuse that I'm aware of, probably because you don't have any control over the remote resource.

That won't work for virtual hosted web sites, which is most web sites, because the unrecognized host name in the Host header which will hit the default host on the target web server instead of the correct virtual host, unless that web server is configured to recognize the foo.ipq.co host name.

that being said you can do this for free @ dyndns with only slightly more effort

Other than the servers checking host per other people's comments, this is basically just how dns works... anybody with a domain can point any subdomain or domain they own to any IP they want. I can't see any practical way around this at the dns level.
