Cette adresse est assignée soit individuellement (attribution statique) par l'administrateur du réseau local dans le [[sous-réseau]] correspondant, soit automatiquement (attribution dynamique) via le protocole [[Dynamic Host Configuration Protocol|DHCP]]. Si l'ordinateur dispose de plusieurs interfaces réseau, chacune d'entre elles disposera alors d'une adresse IP. Un même équipement peut donc avoir plusieurs adresses IP simultanément. Une interface peut également disposer de plusieurs adresses IP<ref>[https://technet.microsoft.com/en-us/library/cc722518.aspx {{lang|en|Configuring Multiple IP Addresses and Gateways}}], technet.microsoft.com.</ref>. Chaque paquet transmis par le protocole IP contient l'adresse IP de l'émetteur ainsi que l'adresse IP du destinataire. Les [[routeur]]s IP acheminent les paquets vers la destination de proche en proche. Certaines adresses IP sont utilisées pour la diffusion ({{lang|en|[[multicast]]}} ou [[Broadcast (informatique)|{{lang|en|broadcast}}]]) et ne sont pas utilisables pour adresser des ordinateurs individuels. La technique ''{{lang|en|[[anycast]]}}'' permet de faire correspondre une adresse IP à plusieurs ordinateurs répartis sur Internet. Les adresses IPv4 sont dites ''publiques'' si elles sont enregistrées et routables sur Internet, elles sont donc uniques ''mondialement''. À l'inverse, les [[Réseau privé|adresses ''privées'']] ne sont utilisables que dans un [[réseau local]], et ne doivent être uniques que dans ce réseau. La [[Network address translation|traduction d'adresse réseau]], réalisée notamment par les {{lang|en|[[box internet]]}}, transforme des ''adresses privées'' en ''adresses publiques'' et permet d’accéder à Internet à partir d'un poste du réseau privé. </textarea><div class="templatesUsed"></div><p id="mw-returnto">Revenir à la page <a href="/wiki/Adresse_IP" title="Adresse IP">Adresse IP</a>.</p> <noscript><img src="https://login.wikimedia.org/wiki/Special:CentralAutoLogin/start?type=1x1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="">Ce document provient de « <a dir="ltr" href="https://fr.wikipedia.org/wiki/Adresse_IP">https://fr.wikipedia.org/wiki/Adresse_IP</a> ».</div></div> <div id="catlinks" class="catlinks catlinks-allhidden" data-mw="interface"></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" > <ul id="footer-info"> </ul> <ul id="footer-places"> <li id="footer-places-privacy"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Privacy_policy/fr">Politique de confidentialité</a></li> <li id="footer-places-about"><a href="/wiki/Wikip%C3%A9dia:%C3%80_propos_de_Wikip%C3%A9dia">À propos de Wikipédia</a></li> <li id="footer-places-disclaimers"><a href="/wiki/Wikip%C3%A9dia:Avertissements_g%C3%A9n%C3%A9raux">Avertissements</a></li> <li id="footer-places-contact"><a href="//fr.wikipedia.org/wiki/Wikipédia:Contact">Contact</a></li> <li id="footer-places-wm-codeofconduct"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Universal_Code_of_Conduct">Code de conduite</a></li> <li id="footer-places-developers"><a href="https://developer.wikimedia.org">Développeurs</a></li> <li id="footer-places-statslink"><a href="https://stats.wikimedia.org/#/fr.wikipedia.org">Statistiques</a></li> <li id="footer-places-cookiestatement"><a href="https://foundation.wikimedia.org/wiki/Special:MyLanguage/Policy:Cookie_statement">Déclaration sur les témoins (cookies)</a></li> <li id="footer-places-mobileview"><a href="//fr.m.wikipedia.org/w/index.php?title=Adresse_IP&action=edit&section=1&mobileaction=toggle_view_mobile" class="noprint stopMobileRedirectToggle">Version mobile</a></li> </ul> <ul id="footer-icons" class="noprint"> <li id="footer-copyrightico"><a href="https://wikimediafoundation.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/static/images/footer/wikimedia-button.svg" width="84" height="29" alt="Wikimedia Foundation" loading="lazy"></a></li> <li id="footer-poweredbyico"><a href="https://www.mediawiki.org/" class="cdx-button cdx-button--fake-button cdx-button--size-large cdx-button--fake-button--enabled"><img src="/w/resources/assets/poweredby_mediawiki.svg" alt="Powered by MediaWiki" width="88" height="31" loading="lazy"></a></li> </ul> </footer> </div> </div> </div> <div class="vector-settings" id="p-dock-bottom"> <ul></ul> </div><script>(RLQ=window.RLQ||[]).push(function(){mw.config.set({"wgHostname":"mw-web.codfw.canary-84779d6bf6-wmcb5","wgBackendResponseTime":187,"wgPageParseReport":{"limitreport":{"cputime":"0.005","walltime":"0.006","ppvisitednodes":{"value":17,"limit":1000000},"postexpandincludesize":{"value":848,"limit":2097152},"templateargumentsize":{"value":0,"limit":2097152},"expansiondepth":{"value":2,"limit":100},"expensivefunctioncount":{"value":0,"limit":500},"unstrip-depth":{"value":0,"limit":20},"unstrip-size":{"value":0,"limit":5000000},"entityaccesscount":{"value":0,"limit":400},"timingprofile":["100.00% 0.000 1 -total"]},"cachereport":{"origin":"mw-web.codfw.canary-84779d6bf6-wmcb5","timestamp":"20241124150742","ttl":2592000,"transientcontent":false}}});});</script> </body> </html>
