Which are your favorite free supported DynamicDNS / DDNS providers and why?
My favorite is:
I use this service with my own domains, but there are many domains with a wide range of cool tld's...
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.
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.
I'm using free ddns at https://free-ddns.com. Simple but it works
