What is a reserved IP address?

A host cannot send an IP packet to a private address unless it is on the same private network as that address. 10.0.0.0 – 10.255.255.255 172.16.0.0 – 172.31.255.255 192.168.0.0 – 192.168.255.255 The block 127.*.*.* is reserved for local software loopback testing 127.0.0.0 – 127.255.255.255 The block 224 – 239.*.*.* is reserved for IP multicasting 224.0.0.0 – 239.255.255.255 The block 240 – 255.*.*.* is reserved 240.0.0.0 – 255.255.255.255 Addresses from within the
