Looks cool. IPv6 support would be neat. Does this work with the AirPort dynamic global hostname? I put my username and password in, but since my IP didn't change since I signed up I couldn't see if it was working right.

Why do you want ipv6 support? There are already ipv6 mechanisms like mobility aren't there (although not set them up yet).

IPv6 mobile address portability attempts to keep your IPv6 address constant as you move around different wireless access points or LANs within a company or ISP network. It doesn't provide a globally static address or way to provide a static hostname.

Even with a static or mostly static IPv6 address the ability to have a dual stack dynamic hostname where both the v4 (that changes a lot) and the v6 (which might change less) is still useful. It is also obviously useful as you roam between office and home and such and want to keep a hostname constant.

Mobile IP in IPv6 is very much meant to keep your stable, global address working while you roam around the global Internet.

The route optimization mechanism means your packets can travel directly between the mobile node's care-of address and the other guy if they both support MIP, so no need to be even on the same continent.

Sadly MIP is mostly dead, though there seems to be a somewhat up to date (2013) Linux impl of Mobile IP v6 and NEMO for IPv4 here: http://umip.org/

My impression is that it was kind of overshadowed by IETF's efforts to make an architecturally pretty fix to the whole locator-vs-ID thing. This is the work leading to the LISP protocol. You can now find papers from Facebook, Cisco, etc advocating its deployment. Hopefully it will get popular at some point.

Will you ban a client if it posts updates on a regular cycle? I got banned from dyndns because I wrote my own client and put it into cron. (I think it's actually smart they banned me, since it was a huge waste of time to update with no new info)

No, it's Dyn's and No-IP's thing.

From FreeDNS news page[1]: "2012-03-29 18:20:33, 2 years ago: Free accounts not accessed at least once every 6 months will be considered dormant and unloaded from memory." What does "dormant" mean here? Do they delete your DNS records? It might not be as draconian as what DynDNS was doing, but certainly a barrier you should consider. [1]: http://freedns.afraid.org/news/

Here's an email I got from FreeDNS last year:

Your account at freedns.afraid.org has not been visited in at least 5 1/2 months.

User: Xxxxx Xxxxx (xxxxxxx) Last visited: 2013-09-21 (169 days ago)

Unless you visit the site anytime in the next 2 weeks, your account will be considered dormant. "Dormant" consists of unloading any stale DNS records from memory which you may have set up in the past.

This stale entries optimization will free up several gigabytes of memory, making it available for active users. This will allow a DNS server to do a cold configuration boot, and load in new zones in a fraction of the time and space.

Users supporting freedns.afraid.org with a premium plan of any kind (even the smallest) will not be affected.

I don't think it's anything incredibly special (especially with the ugly bootstrap theme), and you guys probably all have your own domain names anyhow, but I'm just posting it on the off-chance that it might be useful to someone here. Plus, I quite like 'zzzz' in comparison to the domain names offered by other free dyndns alternatives out there.

I am fairly shocked it took this long for someone to make a DynDNS replacement. I haven't been able to effectively use DynDNS since last century.

What's the technology stack? Would there be a way to persuade you to opensource it?

^^ Seconded.

Is there any particular reason you didn't just add your domain to the pool at https://freedns.afraid.org/ ?

Although this may not be perceived as constructive criticism but freedns is indeed great. It has many features, thousands domains, support for your own domain, perfect availability and it is free. The person behind it seems more interested to provide a free quality service than promote himself.

For anyone building a dynamic IP service, freedns sets the level they should strive for.
