That's pretty interesting. Somewhat like DDNS, but not as useful?
I don't know if I want an ipq.co address, but I just realized - could I use my own DNS hosting (through slicehost, linode, whatever) to assign domain names to arbitrary IP addresses?
Like, if I own garlicgargle.com, and I have another system with a static IP, does that mean I can just assign salty.garlicgargle.com to that IP and it works fine? Sorry for the basic question, I guess I don't understand doing much with DNS beyond the common tasks.
- jrockway 16y agoYes. It's called an A record.
- code_duck 16y agoIt's called a different use of an A record than what I'm used to. I'm talking about some totally unconnected system on a different network. Seems kind of odd to me, what's stopping me from calling my own ip address google.com? I don't know what that would do for me, of course. Like I said, I know that sounds pretty basic but it's a different way of thinking about this for me, i.e. I've realized I could give my home system, which has a static IP, a domain name that is a subdomain of one of our work computers, which would have been really handy like... last year.
- il 16y agoGoogle's domain is pointed at Google nameservers. If you point a domain you control to your own nameserver, you can direct it to any IP you want, on any network.
- code_duck 16y agoAha, that's the catch. Thanks for the info.
- mthoms 16y agoNot necessarily a catch though. Many (most?) registrars and web hosts provide name servers free for their users (GoDaddy lets you do this for example). If you can add/edit DNS records can point a subdomain anywhere you like.
- code_duck 16y agoBut, that doesn't mean I'm free to point evildomain.google.com to anywhere I prefer, right?
- prodigal_erik 16y agoYou can do that, but nobody believes your nameserver is authoritative for questions about google.com, so it will only affect someone whom you can persuade to use yours as their default nameserver. Everyone else who asks the "com" top-level domain nameservers who is authoritative for google.com is going to be sent to GOOG's nameservers, not yours, so names you define will be invisible to them.
- mthoms 16y agoAlso, note that you could have google.evildomain.com - At least until you get a C&D order that is.
- tlrobinson 16y agoDNS is basically a big key-value store. You can point any domain or subdomain to any IP address.
