I saw two IP addresses that I did not understand.


Are these broadcast addresses?

1 Answer 1


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 a valid host address regardless of subnet mask? Oh I guess on a subnet of, or something like that, maybe it is. Jan 3, 2018 at 19:38

    Yes, or You could certainly have a loopback with the 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. Jan 3, 2018 at 19:51
