Applications Of Ipsec
Transport Layer – This layer utilizes UDP and TCP to ensure the correct transmission of information. The transition to IPv6 will take place over a few years, with each IPv4 and IPv6 addresses being used in parallel. However, an increasing quantity of Internet content and purposes will be available only at IPv6 addresses.
