10.0.0.0/8; so much room for activity.
I currently use 10.0.0.0/24 as infrastructure; 10.10.0.0/24 for hard wired devices; 10.20.0.0/24 for wireless devices; and 10.42.0.0/16 for docker containers provisioned by Rancher.
Can you tell what do the values after / denote? Like /8, /24.
I have seen them in many places. I even use /8 in my Wireguard config. But I do not know what it is. I do not even know its name to look it up online.
The term you are looking for is CIDR notation. The / is showing what the subnet mask is. So the subnet mask for a /8 is 255.0.0.0, which would be an extremely large network (over 16 million addresses, this was traditionally known as a Class A).

It's called CIDR notation, the number represents how many bits of the whole address represent the "network" part of the address. /8 is equivalent to a subnet mask of 255.0.0.0
