H\u00e4r f\u00f6rklarar vi de vanligaste fr\u00e5gorna om IP-adresser och visar hur du kan ta reda p\u00e5 din egen IP-adress.<\/p>\n

Vad \u00e4r en IP-adress och vad anv\u00e4nds den till?<\/h2>\n

En IP-adress \u00e4r en individuell kombination av siffror. P\u00e5 samma s\u00e4tt som varje telefon beh\u00f6ver ett telefonnummer och varje hus en gatuadress beh\u00f6ver varje dator ocks\u00e5 ett unikt identifieringsnummer. S\u00e5 snart en anslutning till Internet<\/a> En IP-adress tilldelas varje enhet. Tack vare IP-adressen kan varje enhet identifieras och kontaktas. Smartphones, surfplattor och andra enheter som ansluter till internet f\u00e5r ocks\u00e5 en IP-adress. F\u00f6rkortningen IP st\u00e5r f\u00f6r \"Internet Protocol\", och denna n\u00e4tverksstandard \u00e4r n\u00e5got som liknar det internationella spr\u00e5ket f\u00f6r datorer.<\/p>\n

Hur \u00e4r en IP-adress uppbyggd?<\/h3>\n

Alla IP-adresser<\/a> f\u00f6lja ett enhetligt m\u00f6nster. Det finns f\u00f6r n\u00e4rvarande tv\u00e5 standarder, IPv4 och IPv6. Adresser enligt IPv4-standarden best\u00e5r av fyra siffror i intervallet 0-255 och har h\u00f6gst 12 siffror. Exempel: \"81.9.255.72\". Siffrorna \u00e4r \u00e5tskilda fr\u00e5n varandra med en punkt. Eftersom endast ett begr\u00e4nsat antal kombinationer kan bildas med IPv4-systemet bildas IP-adresser i allt st\u00f6rre utstr\u00e4ckning enligt den nya IPv6-standarden. Adresser i det nya formatet best\u00e5r av \u00e5tta teckenblock som \u00e4r separerade med kolon och inneh\u00e5ller b\u00e5de bokst\u00e4ver och siffror. Beispiel: \u201e2001:0db3:85a8:0000:0000:8a2e:0370:7334\u201c. Om IP-adressen i IPv6-standarden har m\u00e5nga nollor kan dessa ers\u00e4ttas med ytterligare ett kolon.<\/p>\n

Hur kan du ta reda p\u00e5 din egen IP-adress?<\/h3>\n

Du kan snabbt ta reda p\u00e5 din egen IP-adress p\u00e5 Internet. Webbplatser som \"http:\/\/fssecure.t-online.de\/service\/ip\/\" eller \"eigene-IP.de\" visar den inom n\u00e5gra sekunder. I de flesta fall har en enhet ocks\u00e5 en andra IP-adress, den f\u00f6r det egna n\u00e4tverket i hemmet. Dessa interna adresser b\u00f6rjar vanligtvis med \"192\" och kan l\u00e4sas ut direkt p\u00e5 datorn med hj\u00e4lp av \"ipconfig\"-prompten (Windows 7 och 10).<\/p>\n

Vad avsl\u00f6jar IP-adressen om anv\u00e4ndaren?<\/h3>\n

En IP-adress avsl\u00f6jar var en anv\u00e4ndare befinner sig och vilken internetleverant\u00f6r som anv\u00e4nds. Det kan s\u00e5ledes antas att en kund hos Telecom<\/a> har en IP-adress som b\u00f6rjar med 212, 81 eller 91. Platsen best\u00e4ms via den s\u00e5 kallade uppringningsnoden. I regel \u00e4r detta h\u00f6gst n\u00e5gra kilometer bort, i stadsomr\u00e5den n\u00e4rmare. Detta inneb\u00e4r att den geografiska lokaliseringen \u00e4r relativt exakt.<\/p>\n

Internetleverant\u00f6rerna kan dessutom exakt sp\u00e5ra varje kunds datastr\u00f6m och se vad som s\u00f6ks p\u00e5 n\u00e4tet, vilka webbplatser som bes\u00f6ks eller vilka filer som laddas ner. Enligt g\u00e4llande lagstiftning \u00e4r Internetleverant\u00f6rerna dock skyldiga att radera alla historikuppgifter n\u00e4r en internetsession \u00e4r avslutad. Informationen om vilken IP-adress som tillh\u00f6r vilken kund f\u00e5r lagras i h\u00f6gst sju dagar. Under denna tid kan ett domstolsbeslut inh\u00e4mtas f\u00f6r att fastst\u00e4lla bostadsadress och kontaktuppgifter f\u00f6r respektive anv\u00e4ndare. Men endast vid motiverad misstanke, t.ex. om upphovsr\u00e4ttsskyddat material delas via en fildelningssida eller om barnporr laddas ner. Generellt sett beh\u00e5ller en kund sin IP-adress endast under den tid som en internetsession varar; n\u00e4sta g\u00e5ng han ringer in f\u00e5r han en ny IP-adress. IP-adressen \u00e4ndras allts\u00e5 st\u00e4ndigt, den tilldelas dynamiskt av internetleverant\u00f6ren.<\/p>\n

Kan du d\u00f6lja din egen IP-adress?<\/h3>\n

Det \u00e4r inte m\u00f6jligt att helt d\u00f6lja din IP-adress. Det finns dock program som JAP eller Tor som kan anv\u00e4ndas f\u00f6r att d\u00f6lja dina egna aktiviteter p\u00e5 Internet. Anv\u00e4ndningen av s\u00e5dana tj\u00e4nster kan dock s\u00e4nka internethastigheten.<\/p>","protected":false},"excerpt":{"rendered":"
