First, ipconfig /release is executed to force the client to immediately give up its lease by sending the server a DHCP release notification which updates the server's status information and marks the old client's IP address as "available". Then, the command ipconfig /renew is executed to request a new IP address.
The client must send the server identification option in the DHCPREQUEST message, indicating the server whose offer the client has selected. [8]: Section 3.1, Item 3 When other DHCP servers receive this message, they withdraw any offers that they have made to the client and return their offered IP address to the pool of available addresses.
Whereas the words server and client may refer either to a computer or to a computer program, server-host and client-host always refer to computers. The host is a versatile, multifunction computer; clients and servers are just programs that run on a host. In the client–server model, a server is more likely to be devoted to the task of serving.
In computer networking, a network service is an application running at the network application layer and above, that provides data storage, manipulation, presentation, communication or other capability which is often implemented using a client–server or peer-to-peer architecture based on application layer network protocols.
A host is a node that participates in user applications, either as a server, client, or both. A server is a type of host that offers resources to the other hosts. Typically a server accepts connections from clients who request a service function. [4] Every network host is a node, but not every network node is a host.
The server is often (but not always) on another computer system, in which case the client accesses the service by way of a network. [2] A client is a computer or a program that, as part of its operation, relies on sending a request to another program or a computer hardware or software that accesses a service made available by a server (which ...
Differentiated services or DiffServ is a computer networking architecture that specifies a mechanism for classifying and managing network traffic and providing quality of service (QoS) on modern IP networks.
nslookup, used to query a DNS server for DNS data (deprecated on Unix systems in favour of host and dig; still the preferred tool on Microsoft Windows systems). vnStat, useful command to monitor network traffic from the console. vnstat allows to keep the traffic information in a log system to be analyzed by third party tools.
