What does 10.0.0.0/32 mean?

Question

I saw two IP addresses that I did not understand.

Are these broadcast addresses?

Those are host addresses. Addresses using a 32-bit mask only have a single address, and they are addresses that are assigned to a host.

Is 10.0.0.0 a valid host address regardless of subnet mask? Oh I guess on a subnet of 8.0.0.0/4, or something like that, maybe it is.

Yes, or 8.0.0.0/6. You could certainly have a loopback with the 10.0.0.0/32 address, or you could have it as a host address in a larger network. I have heard people insist that any address that has 0 or 255 in the last octet is not a valid host address, even though that really isn't the case.

That's probably exactly what confused the asker.
