CirrusResolving DNS, and dynamically selecting pool
The problem: Some LAN hosts are not permitted outbound access to the internet through the firewall, and yet, they need access to github.com. Unfortunately, github's published CIDR ranges are enormous...
you can simple create pool member using hostname instead of ip address

CirrusUsing FQDN Nodes seems to have totally solved it. Thanks! I didn't know of that capability before...

CirrusAdditionally, when you create an FQDN node by adding a pool member, the TTL options are suppressed, and it is created with a default value of 3600 seconds.
Therefore, the best option to solve your problem with the IP change for the host github.com quickly would be to create an FQDN node under "Nodes," as this will give you the option to set the TTL to your preferred time.
If you also want to change the TTL of the FQDN node created through the addition of a pool member, simply access the node and adjust it as you prefer.
I used gitlab.com as an example host.
