-- another edit --

network id would actually be 192.168.1.56 or 192.168.1.64

-- end edit --

/29 means there are 8 ip addresses

192.168.1.58 is the network id .... it counts as 0, not usable.

.59 = 1

.60 = 2

.61 = 3

ect....

192.168.1.65 is the broadcast ip address, it counts as 7 and is not usable (0-7 = 8 numbers)

it would be useful to note that 192.168.1.60/29 is invalid and would never be in a routing table .... but it can be used as shorthand to indicate that the ip address belongs to an interface and it uses a /29 subnet mask
