In theory this might be solved via some scripting, maybe via a DNS
server like powerDNS?
## Alternative solution with BIND
The bind DNS server, which is not usually deployed in a kubernetes
cluster, supports **views**. Views enable different replies to the
same query depending on the source IP address. Thus in theory
something like that could be done, assuming a secondary zone
*example.org*:
* If the request comes from the kubernetes cluster, return a CNAME
back to example.com.
* If the request comes from outside the kubernetes cluster, return an
A entry with the static IP
* Unsolved: how to match on the AAAA entries (because we don't CNAME
with the added A entry)
## Other solution?
As you can see, mixing the dynamic IP generation and coupling it with
