IP in MAC naslovi: Osnove za razumevanje
1 / 6
Uvod v naslavljanje
Predstavljaj si, da si v velikem nakupovalnem centru in iščeš specifično trgovino. Brez številk trgovin ali zemljevida bi bilo to skoraj nemogoče, kajne? Enako velja za računalniška omrežja - vsaka naprava potrebuje edinstven naslov za komunikacijo.
V omrežjih imamo dva glavna tipa naslovov: IP naslov in MAC naslov. IP naslov je kot naslov stanovanja (se lahko spremeni), MAC naslov pa je kot tvoj EMŠO (se ne spreminja).
IPv4 uporablja 32-bitne naslove in jih zmanjkuje, medtem ko IPv6 z 128-bitnimi naslovi rešuje ta problem. Omrežna kartica (NIC) ima vgrajen MAC naslov, oktet pa je skupina 8 bitov, iz katerih je sestavljen IPv4 naslov.
Pomembno: IP naslovi delujejo med različnimi omrežji (internet), MAC naslovi pa samo znotraj lokalnega omrežja.
IPv4 naslovi
IPv4 naslovi so kot telefonske številke interneta. Imajo 32 bitov, kar pomeni približno 4,3 milijarde možnih naslovov - in ja, skoraj so jih že porabili!
Zapisujejo se v decimalni obliki s pikami: štiri števila (okteti) med 0 in 255, ločena s pikami. Primer: 192.168.1.10. Vsak IP naslov ima omrežni del (pove, v katerem omrežju si) in gostiteljski del (katera specifična naprava si).
Poznati moraš razliko med javnimi in zasebnimi IP naslovi. Javni IP dobi tvoj router od ponudnika interneta in je edinstven na celem svetu. Zasebni IP pa uporabljajo naprave doma - najpogosteje v območju 192.168.x.x.
Nasvet za teste: Zapomni si območje 192.168.0.0 - 192.168.255.255 za zasebne IP-je!
MAC naslovi
MAC naslov je kot "prstni odtis" tvoje omrežne kartice. Je 48-bitni in nespremenljiv - tovarniško določen in edinstven za vsako omrežno kartico.
Zapisuje se v šestnajstiškem sistemu: šest parov heksadecimalnih števk, ločenih z dvopičji ali vezaji. Primer: 00:1A:2B:3C:4D:5E. Heksadecimalne števke so 0-9 in A-F.
Prvi trije pari predstavljajo OUI (organizacijski identifikator) - povedo, kdo je proizvajalec kartice. Zadnji trije pari so edinstvena serijska številka. Tako lahko iz MAC naslova ugotoviš, ali imaš Apple, Intel ali drugo omrežno kartico!
Zanimivost: S pomočjo OUI lahko ugotoviš, ali nekdo uporablja iPhone (Apple OUI) ali Android telefon!
IPv6 naslovi in praktični primeri
IPv6 rešuje problem pomanjkanja IPv4 naslovov z 128-bitnimi naslovi - to je toliko naslovov, da bi lahko dal vsakemu pesku na Zemlji svoj naslov! Zapisuje se v osmih skupinah po štiri heksadecimalne števke: 2001:0db8:85a3:0000:0000:8a2e:0370:7334.
Za krajšanje lahko izpustiš vodilne ničle in eno zaporedje ničel zamenjaš z :: (samo enkrat!). Zgornji primer postane: 2001:db8:85a3::8a2e:370:7334.
Praktičen primer analize: IP naslov 172.16.30.56 spada v zasebno območje (172.16.0.0-172.31.255.255). MAC naslov 3C-FD-FE-0A-B1-C2 ima OUI 3C-FD-FE, kar pripada Apple napravam.
Tip za teste: IPv6 krajšanje lahko uporabiš samo enkrat - sicer ne veš, koliko ničel je na vsakem mestu!
Razlike in skupno delovanje
Najpomembnejša razlika: IP naslovi delujejo na omrežni plasti (logična) in omogočajo komunikacijo med različnimi omrežji, MAC naslovi pa na povezovalni plasti (fizična) znotraj lokalnega omrežja.
Ko pošiljaš sporočilo prijatelju preko interneta, tvoj računalnik uporabi njegov IP naslov za usmerjanje, MAC naslov pa za komunikacijo z domačim routerjem.
Predstavljaj si to tako: IP naslov je kot GPS koordinate hiše (globalni naslov), MAC naslov pa kot ime osebe v hiši (lokalni identifikator).
Ključno za razumevanje: IP = "Kje si?" (lokacija), MAC = "Kdo si?" (identiteta) - to ti bo pomagalo pri vseh nalogah!

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.

I think it’s very much worth it and you’ll end up using it a lot once you get the hang of it and even after looking at others notes you can still ask your Artificial intelligence buddy the question and ask to simplify it if you still don’t get it!!! In the end I think it’s worth it 😊👍 ⚠️Also DID I MENTION ITS FREEE YOU DON’T HAVE TO PAY FOR ANYTHING AND STILL GET YOUR GRADES IN PERFECTLY❗️❗️⚠️

Knowunity is the BEST app I’ve used in a minute. This is not an ai review or anything this is genuinely coming from a 7th grade student (I know 2011 im young) but dude this app is a 10/10 i have maintained a 3.8 gpa and have plenty of time for gaming. I love it and my mom is just happy I got good grades

Not only did it help me find the answer but it also showed me alternative ways to solve it. I was horrible in math and science but now I have an a in both subjects. Thanks for the help🤍🤍

The app's just great! All I have to do is enter the topic in the search bar and I get the response real fast. I don't have to watch 10 YouTube videos to understand something, so I'm saving my time. Highly recommended!

I found this app a couple years ago and it has only gotten better since then. I really love it because it can help with written questions and photo questions. Also, it can find study guides that other people have made as well as flashcard sets and practice tests. The free version is also amazing for students who might not be able to afford it. Would 100% recommend

Best app if you're in Highschool or Junior high. I have been using this app for 2 school years and it's the best, it's good if you don't have anyone to help you with school work.😋🩷🎀
