Vrednost polja je 4.</li> <li><i>Dužina Internet Zaglavlja</i> (IHL) (4 bita): Dužina zaglavlja u 32-bitnoj reči. Minimalna vrednost je pet za minimalnu dužinu zaglavlja od 20 bajta.</li> <li><i>Tip servisa</i> TOS (<a href="/wiki/Engleski_jezik" title="Engleski jezik">engleski</a>: <span lang="en"><i>Type of Service</i></span>) (8 bita): U prethodnom opisu servisa, ovo polje se odnosilo na polje tip Servisa i određivalo je pouzdanost, prednost, odlaganje i parametre propusne moći. Ovakva iterpretacija je sada zamenjena. Prvih 6 bita polja Tipa Servisa sada pripada polju DS (<a href="/wiki/Engleski_jezik" title="Engleski jezik">engleski</a>: <span lang="en"><i>Differentiated Services</i></span>), a ostala 2 bita rezervisana su za polje ECN (<a href="/wiki/Engleski_jezik" title="Engleski jezik">engleski</a>: <span lang="en"><i>Explicit Songestion Notification</i></span>).</li> <li><i>Ukupna dužina</i> (16 bita): Ukupna dužina datagrama, uključujući zaglavlje i podatke, izraženo je u bajtovima (oktetima).</li> <li><i>Identifikacija</i> (16 bita): Niz brojeva, koji zajedno sa izvorišnom adresom, odredišnom adresom i korisničkim protokolom namerava da jedinstveno identifikuje paket. Prema tome, ovaj broj bi trebao da bude jedinstven za izvorišnu adresu, odredišnu adresu i korisnički protokol datagrama dok god je on u internetu.</li> <li><i>Kontrolni bitovi</i> (3 bita): Samo dva od ovih bita su trenutno definisana. MF (<a href="/wiki/Engleski_jezik" title="Engleski jezik">engleski</a>: <span lang="en"><i>More Fragment</i></span>) se koristi za fragmentaciju i ponovno sklapanje, kao što je malopre objašnjeno. Bit DF (<a href="/wiki/Engleski_jezik" title="Engleski jezik">engleski</a>: <span lang="en"><i>Dont Fragment</i></span>) zabranjuje fragmentaciju kada se to traži. Ovaj bit može biti od velike koristi kada se zna da destinacija nema kapaciteta da sklopi fragmente. Ipak, ako je ovaj bit postavljen, paket će biti odbačen ako premaši maksimalnu veličinu mreže na nekoj ruti. Da se ovo ne bi desilo, bilo bi pametno koristiti izvorišno rutiranje da bi se zaobišle mreže koje imaju definisanu malu maksimalnu veličinu paketa.</li> <li><i>Mesto fragmenta</i> (13 bita): Pokazuje gde je u originalnom datagramu mesto ovom fragmentu, iskazano u 64 bita. To znači da fragmenti koji nisu poslednji fragment moraju da sadrže polje podataka koje je deljivo sa 64 bita u dužini.</li> <li><i>Vreme života</i> (TTL) (8 bita): Pokazuje koliko dugo, u skokovima, je dozvoljeno datagramu da bude u internetu. Svaki ruter koji procesira datagram mora da smanji TTL za najmanje jedan, tako da je TTL donekle sličan brojaču skokova.</li> <li><i>Protokol</i> (8 bita): Pokazuje protokol višeg nivoa kome treba proslediti paket; prema tome, ovo polje identifikuje tip zaglavlja segmenta (<a href="/wiki/Transportni_sloj" title="Transportni sloj">sloj transporta</a>). Vrednosti 1 (00000001) za <a href="/wiki/ICMP" class="mw-redirect" title="ICMP">ICMP</a>, 6 (00000110) za TCP, 17 (00010001) za UDP</li> <li><i>Zaštitna suma (Čeksuma)</i> (16 bita): Kod za detektovanje greške koji je privezan samo zaglavlju. Zbog menjanja nekih polja tokom puta (npr. vreme u životu, fragmentaciona polja), ovo polje se reverifikuje i procenjuje u svakom ruteru. Polje se formira tako što se uzmu jedinice iz 16 bita i dodaju se sve jedinice iz svih 16-bitnih reči u zaglavlju. Zbog računanja, polja čeksume su inicijalizovana na vrednost nula.</li> <li><i>Izvorišna adresa</i> (32 bita): Kodirano da bi se dozvolile različite kombinacije bita za specificiranje mreže ili sistema prikačenog na mrežu.</li> <li><i>Odredišna adresa</i> (32 bita): Iste katakteristike kao izvorišna adresa.</li> <li><i>Opcije (promenljivo)</i>: Kodira opcije tražene od strane pošiljaoca.</li> <li><i>Punjenje (promenljivo)</i> (<a href="/wiki/Engleski_jezik" title="Engleski jezik">engleski</a>: <span lang="en"><i>Padding</i></span>): Koristi se da bi se moglo garantovati da je zaglavlje datagrama spoj 32-bitnih dužina.</li> <li><i>Podaci višeg sloja (promenljivo)</i>: Ovo polje mora biti spoj 8-bitnih dužina celih brojeva. Maksimalna dužina datagrama (polja podataka + zaglavlja) je 65,535 bajtova</li></ul> <div class="mw-heading mw-heading2"><h2 id="Reference">Reference</h2><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=IPv4&veaction=edit&section=2" title="Uredi odjeljak Reference" class="mw-editsection-visualeditor"><span>uredi</span></a><span class="mw-editsection-divider"> | </span><a href="/w/index.php?title=IPv4&action=edit&section=2" title="Uredi kôd odjeljka Reference"><span>uredi kod</span></a><span class="mw-editsection-bracket">]</span></span></div> <style data-mw-deduplicate="TemplateStyles:r42389381">.mw-parser-output .reflist{font-size:90%;margin-bottom:0.5em;list-style-type:decimal}.mw-parser-output .reflist .references{font-size:100%;margin-bottom:0;list-style-type:inherit}.mw-parser-output .reflist-columns-2{column-width:30em}.mw-parser-output .reflist-columns-3{column-width:25em}.mw-parser-output .reflist-columns{margin-top:0.3em}.mw-parser-output .reflist-columns ol{margin-top:0}.mw-parser-output .reflist-columns li{page-break-inside:avoid;break-inside:avoid-column}.mw-parser-output .reflist-upper-alpha{list-style-type:upper-alpha}.mw-parser-output .reflist-upper-roman{list-style-type:upper-roman}.mw-parser-output .reflist-lower-alpha{list-style-type:lower-alpha}.mw-parser-output .reflist-lower-greek{list-style-type:lower-greek}.mw-parser-output .reflist-lower-roman{list-style-type:lower-roman}</style><div class="reflist"> <div class="mw-references-wrap"><ol class="references"> <li id="cite_note-1"><span class="mw-cite-backlink"><a href="#cite_ref-1">↑</a></span> <span class="reference-text"><a rel="nofollow" class="external free" href="http://www.cisco.com/en/US/docs/internetworking/technology/handbook/Internet-Protocols.html">http://www.cisco.com/en/US/docs/internetworking/technology/handbook/Internet-Protocols.html</a></span> </li> </ol></div></div>    </div><noscript><img src="https://auth.wikimedia.org/loginwiki/wiki/Special:CentralAutoLogin/start?useformat=desktop&type=1x1&usesul3=1" alt="" width="1" height="1" style="border: none; position: absolute;"></noscript> <div class="printfooter" data-nosnippet="" lang="sh-Latn" dir="ltr">Izvor: <a dir="ltr" href="https://sh.wikipedia.org/w/index.php?title=IPv4&oldid=42406699">https://sh.wikipedia.org/w/index.php?title=IPv4&oldid=42406699</a></div></div> <div id="catlinks" class="catlinks" data-mw="interface"><div id="mw-normal-catlinks" class="mw-normal-catlinks"><a href="/wiki/Posebno:Kategorije" title="Posebno:Kategorije">Kategorija</a>: <ul><li><a href="/wiki/Kategorija:Internet" title="Kategorija:Internet">Internet</a></li></ul></div></div> </div> </main> </div> <div class="mw-footer-container"> <footer id="footer" class="mw-footer" lang="sh-Latn" dir="ltr"> <ul id="footer-info"> <li id="footer-info-lastmod"> Ova stranica je posljednji put izmijenjena 23. januara 2025. u 14:38.</li> <li id="footer-info-copyright">Tekst je dostupan pod licencom <a rel="nofollow" class="external text" href="https://creativecommons.org/licenses/by-sa/4.0/deed.en">Creative Commons Attribution-ShareAlike</a>; mogu se primijeniti i dodatni uslovi.
