Link-local addresses may be assigned manually by an administrator or by automatic operating system procedures. In Internet Protocol (IP) networks, they are assigned most often using stateless address autoconfiguration, a process that often uses a stochastic process to select the value of link-local addresses, assigning a pseudo-random address that is different for each session.
A public IP address is a globally routable unicast IP address, meaning that the address is not an address reserved for use in private networks, such as those reserved by RFC 1918, or the various IPv6 address formats of local scope or site-local scope, for example for link-local addressing. Public IP addresses may be used for communication ...

A unique local address (ULA) is an Internet Protocol version 6 (IPv6) address in the address range fc00:: / 7. [1] These addresses are non-globally reachable [ 2 ] (routable only within the scope of private networks, but not the global IPv6 Internet).
Static routing may have the following uses: When using static address configuration (in the absence of DHCP or Router Advertisements) it can be used to provide a default route, forming a special case of the longest prefix match as it has a prefix length of zero and therefore always matches, and always matches last.
The IP address of a public server is also important, similar in global uniqueness to a postal address or telephone number. Both IP address and port number must be correctly known by all hosts wishing to successfully communicate. Private IP addresses as described in RFC 1918 are usable only on private networks not directly connected to the internet.
The host broadcasts an ARP request containing the node's IP address, and the node with the corresponding IP address returns an ARP reply that contains its MAC address. ARP has been implemented with many combinations of network and data link layer technologies, such as IPv4 , Chaosnet , DECnet and Xerox PARC Universal Packet (PUP) using IEEE 802 ...
MAC addresses need to be individually configured on the servers by an administrator. RARP is limited to serving only IP addresses . Reverse ARP differs from the Inverse Address Resolution Protocol (InARP), which is designed to obtain the IP address associated with a local Frame Relay data link connection identifier. [ 2 ]
