Oh I totally agree with what you are saying. A DNS change may be lower cost than running Swift config/management commands. At the very least, ops already know how to do DNS updates, regardless of it's "cost", where they have to learn how to do Swift management. I was simply adding clarity to th

While your correct that a chassis replacement can avoid data rebalancing in the FQDN case if you update DNS, you can actually do the same today with the IP-based system. You can use the set_info command of swift-ring-builder to change the IP for existing devices and this avoids any rebalancing i

I would like to discuss this topic more deeply. I understand we need to prepare DNS systems and add a lot of operational complexity and burden to use the DNS system when we use FQDN in Ring files. However I think most datacenter have DNS systems to manage network resources such as ip addresses

Using hostnames instead of IPs is, as mentioned above, something under consideration in that patch. However, note that until now, we've intentionally kept it as just IP addresses since using hostnames adds a lot of operational complexity and burden. I realize that hostnames may be preferred in
