Correct. I used NOIP for years until I realized that 1) my IP address is static and 2) my home IP address was being exposed. (Pretty obvious I know but sometimes I am slow on the uptake ๐)
My solution was to get a $5 per month vps and reverse proxy and reverse ssh tunnels.
The $5 / month VPS ($60/year) was pretty much the cost of NOIP per year to use custom domains.
May I ask what type of commercial web projects you have? Not looking for trade secrets but just a general, big picture overview.
Thanks
