dns.he.net is free for many zones but you need your own domain.

...or just spend like 2$ or so over at gandi.net. Great provider and also supports open source.

I use https://www.duckdns.org/: it's free, reliable, and supported.


http://www.duckdns.org as @eduperez said, I use it for a number of years now, and it just works, is free, and has decent installation instructions.

EDIT: the link was not working (probably never worked) fixed by adding www.

One more vote for freedns.afraid.org
dynv6.com - some interesting IPv6 related functionality

I have an afraid account to "own a domain" then since they only allow 5 subdomains for free, configure a subdomain to have a NS record pointing to the dns.he.net nameserver, for practically unlimited sub-sub-domains.
