I had issues with my sophos xg virtual appliance and ended up installing from scratch. I was using sophos DDNS and now I cannot register for the same hostname I had before. Is there time when previous hostname expires so I can add it back to DDNS config? Right now it still resolves to my IP, but im worried that my ISP changes my IP and it wont resolve correctly anymore.
P.S. It would be very difficult for me to hunt down every place I am using previous DDNS hostname and update with new one - I have quite a bit of things running on my home network. Taht is why I am trying to keep old one alive.
