Why each option
An IP address is a unique numeric logical identifier assigned exclusively to one host or interface on a network.
An IP address is not assigned to multiple hosts - broadcast and multicast addresses serve that purpose and are distinct concepts.
IPv4 addresses are 32 bits and IPv6 are 128 bits - 30 bits is not the length of any standard IP address format.
A physical address describes a MAC address at Layer 2, not an IP address, which is a logical Layer 3 identifier.
An IP address is a logically assigned, unique numeric identifier that identifies a single host or interface within a network, enabling routing and communication between devices. IPv4 addresses are 32 bits and IPv6 addresses are 128 bits, and each uniquely identifies one endpoint. This uniqueness and logical assignment distinguish IP addresses from physical (MAC) addresses and multicast or broadcast addresses.
