DynDNS now aggressively removes active domains from their system

17/06/2012

A couple of days ago I noticed that some of my domains stopped working. A bit befuddled at first, I found that all of them were actually CNAME:s for a DynDNS domain I had set up back in 2006. It had always been a “set it and forget it” solution – until now. Still confused, I logged onto my account and found that the domains were gone. Checked the mail and confirmed my suspicion – the domains had been deleted due to inactivity:

What I found really poor about this email was how little warning you got – it’s five days, and then your domains are gone.

“But it’s not a problem”, I thought – I could just register the domains again!

Nope:

Apparently, at some point DynDNS decided that subdomains are a premium. (Unless you like really clunky domain names that start with dyndns.)

I want to clarify that I do not in any way feel entitled to the domains or DNS service I received from DynDNS. However, I do feel their business practice has become shadier and shadier over the years – starting off with limiting the number of domains per free account, cutting off access to domains and now apparently deleting active domains with just a few days notice.

The whole oredeal reminded me of an article which debated that people who do not own their domains are “second-class citizens” of the web. That is, if you rely on domains purchased by other companies or even other people (as with the free DNS service offered by afraid.org) you never know if these domains will be around tomorrow.

Updating LoopiaDNS from Tomato and DD-WRT firmware

30/01/2012

Loopia is one of the largest Swedish hosting providers and offers a free dynamic DNS service for any domain you own.

They have a great API which can be updated with a number of dynamic DNS clients. They also provide the possibility to update via a HTTP GET request, which we can use in Tomato and DD-WRT.

Tomato
Go to Basic -> DDNS, select Custom URL as service and enter the URL below, swapping username, password and domain.com for your own values:

https://username:password@dns.loopia.se/XDynDNSServer/XDynDNS.php?hostname=domain.com&myip=@IP

If you want to update multiple hostnames to the routers IP address, you can use comma delimited values in hostname, for example:

hostname=domain.com,sub.domain.com,anotherdomain.com

Example:

If you have a wildcard record (*.domain.com) it will get wiped, unless you append

&wildcard=NOCHG

to your request. Read this page for more info. (Swedish)

DD-WRT

Updating LoopiaDNS from DD-WRT can be done via a startup script, check this forum post for instructions.
