In general, there is a network interface for each network card (for computers that have several network cards). A network card (Ethernet or wifi) has a mac address, which identifies the network card on the network. To operate a network card, you must configure the interface that corresponds to it. The if config command allows you to know the network configuration and configure the network by hand or in a script. On the internet, stations called hosts have IP addresses, which allow them to be identified, but a host can also often be designated by a host name or domain name (like google.Com). The DNS (domain name system) was designed to solve this problem, by offering a hierarchical model. Each machine (printer, terminal, server, etc.) connected to a network is assigned a small name. This name is unique within the domain to which it belongs. Thus, for the domains domain1.Com and domain2.Com, we can have two machines with similar or different names.\u003c\/p\u003e\u003cdiv class=\"aw-variant-hidden-subtitle-div\" id=\"aw-variant-subtitle-9786205865620\"\u003e\u003ch3\u003eNetwork and Database Administration\u003c\/h3\u003e\u003c\/div\u003e","brand":"Autorenwelt Shop","offers":[{"title":"Softcover - 9786205865620","offer_id":46455155982661,"sku":"9786205865620","price":79.9,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0622\/files\/774504a9-caa2-4711-b9c3-1e9cf0d5bb79.jpg?v=1758947786","url":"https:\/\/shop.autorenwelt.de\/products\/the-traffic-manager-von-abdoul-hamid-derra","provider":"Autorenwelt Shop","version":"1.0","type":"link"}
