- - - - A P2P application allows a device to act as both a client
        and a server within n the same
        communication.
        
        P2P applications require that
        each end device provides a user
        interface and run a background
        service
      - Common P2P Application
        
        Common P2P networks include G2, Bitcoin, BitTorrent, eDonkey
        
        Some P2P applications are based on
        the Gnutella protocol, where each
        user shares whole files with other users
        
        Many P2P applications allow users to
        share pieces of many files with each
        other at the same time (this is
        BitTorrent technology
- - - - 1)When a client makes a query, the server’s DNS process first looks at its own records to resolve the name
        2)If unable to resolve, it contacts other
        servers to resolve the name.
        3)The server temporarily stores the numbered address in the event that the same name is requested again.
        4)The ipconfig /displaydns command displays all of the cached DNS entries
        on a Windows PC
        
        The NSlookup Command
        
        a utility that allows a user to manually query the name servers to resolve a given host.
        
        Can also be used to troubleshoot name resolution issues and to verify the current status of the name servers.
        
        Dynamic Host Configuration Protocol
        
        1)assignment of IPv4 addresses, subnet masks, gateways, and other
        parameters.
        2)distributed addresses are
        leased for a set period of time, then
        returned to pool for reuse.
        3)s usually employed for end
        user devices. Static addressing is
        used for network devices, such asgateways,switches, servers, and
        printers.
