CentOS - Apr 2014 - Death of dyndns

I'm running two servers, one with a fixed IP address
and the other with a dynamic address.

This is probably a very ignorant question,
but what does dyndns do that I could not do myself?

But what would you like to do, but can not do, at this present time ?

   Our systems are exclusively Centos. No Micro$oft Windoze here.

In principle, nothing. But you aren't their use case. At wikipedia's  
page on dyn is, "Dyn was conceived as an open source, community-led  
student project back by Jeremy Hitchcock, Tom Daly, Tim Wilde and  
Chris Reinhardt while pursuing undergraduate studies at Worcester  
Polytechnic Institute.[2] In the beginning, Dyn enabled students to  
access lab computers and print documents remotely. The project quickly  
outgrew its original purpose and soon gravitated towards domain name  
system (DNS) services. The first iteration was a free dynamic DNS  
service known as DynDNS, which allowed users to register a subdomain  
that points to a computer with regularly changing IP addresses, such  
as those served by many consumer-level Internet service providers. An  
update client installed on the user's computer, or built into a  
networked device, such as a router or webcam, keeps the hostname up to  
date with its current IP address.

"This free service eventually became costly for the founders to  
support. Looking to gauge interest, the project was set to be shut  
down unless users were able to reach a $25,000 fundraising goal. They  
ended up raising over $40,000." There's more.

So with sufficient free time and education and resources anyone could  
do what dyn did. They commodified it and made it easy for  
non-specialists, that's all.

As a replacement http://www.duckdns.org/ seems the easiest to
setup/use. Maybe check if you can do the same yourself?

If you are interested in DIY you could just run your own dns server
(refer to [0]) on your server (the one with the static ip address) and
implement dyndns with your own domain.
