Communication and Internet Technology: Address Resolution between IPv4 and IPv6, and Mobile IP (Part 5 of 6)
IPv4 address is a stateful address. This means that, if a node moves from one subnet to another, the user has to either reconfigure the IP address or request for a new IP address from dynamic host configuration protocol. Whereas, IPv6 supports a stateless auto configuration address. Thus, with IPv6, while moving from a subnet to another, a host can generate its own IP address
Solar Optimism Needs to be Back in India
Sustainable growth of the solar energy industry depends on successful management of photovoltaic (PV) waste.
