Tutaj wyja\u015bniamy najcz\u0119stsze pytania dotycz\u0105ce adres\u00f3w IP i pokazujemy, jak znale\u017a\u0107 sw\u00f3j w\u0142asny adres IP.<\/p>\n

Co to jest adres IP i jaki jest jego cel?<\/h2>\n

Adres IP jest indywidualn\u0105 kombinacj\u0105 liczb. Tak jak ka\u017cdy telefon potrzebuje numeru telefonu, a ka\u017cdy dom potrzebuje adresu zamieszkania, tak ka\u017cdy komputer potrzebuje r\u00f3wnie\u017c niepowtarzalnego numeru identyfikacyjnego. Jak tylko po\u0142\u0105czenie z Internet<\/a> istnieje, przypisany jest adres IP. Adres IP umo\u017cliwia zidentyfikowanie i skontaktowanie si\u0119 z ka\u017cdym urz\u0105dzeniem. Smartfony, tablety i inne urz\u0105dzenia, kt\u00f3re \u0142\u0105cz\u0105 si\u0119 z Internetem, r\u00f3wnie\u017c otrzymuj\u0105 adres IP. Skr\u00f3t IP oznacza \"Internet Protocol\", ten standard sieciowy jest czym\u015b w rodzaju mi\u0119dzynarodowego j\u0119zyka komunikacyjnego dla komputer\u00f3w.<\/p>\n

Jaka jest struktura adresu IP?<\/h3>\n

Wszystkie adresy IP<\/a> maj\u0105 jednolity wz\u00f3r. Obecnie istniej\u0105 dwa standardy, IPv4 i IPv6. Adresy wed\u0142ug standardu IPv4 sk\u0142adaj\u0105 si\u0119 z czterech cyfr w zakresie od 0 do 255 i maj\u0105 maksymalnie 12 cyfr. Przyk\u0142ad: \"81.9.255.72\". Liczby s\u0105 oddzielone kropk\u0105. Poniewa\u017c jednak w systemie IPv4 mo\u017cna utworzy\u0107 tylko ograniczon\u0105 liczb\u0119 kombinacji, adresy IP s\u0105 coraz cz\u0119\u015bciej tworzone zgodnie z nowym standardem IPv6. Adresy w nowym formacie sk\u0142adaj\u0105 si\u0119 z o\u015bmioznakowych blok\u00f3w oddzielonych dwukropkami i zawieraj\u0105cych zar\u00f3wno litery, jak i cyfry. Beispiel: \u201e2001:0db3:85a8:0000:0000:8a2e:0370:7334\u201c. Je\u015bli adres IP w standardzie IPv6 ma wiele zer, mo\u017cna je zast\u0105pi\u0107 dodatkowym dwukropkiem.<\/p>\n

Jak mog\u0119 dowiedzie\u0107 si\u0119, jaki jest m\u00f3j w\u0142asny adres IP?<\/h3>\n

W Internecie mo\u017cesz szybko dowiedzie\u0107 si\u0119, jaki jest Tw\u00f3j w\u0142asny adres IP. Strony internetowe takie jak \"http:\/\/fssecure.t-online.de\/service\/ip\/\" lub \"eigene-IP.de\" pokazuj\u0105 to w ci\u0105gu kilku sekund. W wi\u0119kszo\u015bci przypadk\u00f3w urz\u0105dzenie posiada drugi adres IP, czyli adres w\u0142asnej sieci w domu. Te wewn\u0119trzne adresy rozpoczynaj\u0105 si\u0119 zazwyczaj od \"192\" i mog\u0105 by\u0107 odczytane bezpo\u015brednio na komputerze za pomoc\u0105 komendy \"ipconfig\" (Windows 7 i 10).<\/p>\n

Co dany adres IP ujawnia o u\u017cytkowniku?<\/h3>\n

Adres IP ujawnia, gdzie znajduje si\u0119 u\u017cytkownik i z us\u0142ug jakiego dostawcy Internetu korzysta. Mo\u017cna wi\u0119c za\u0142o\u017cy\u0107, \u017ce klient firmy Telekom<\/a> ma adres IP rozpoczynaj\u0105cy si\u0119 od 212, 81 lub 91 Lokalizacja jest okre\u015blana za pomoc\u0105 tzw. w\u0119z\u0142a dial-in. Zazwyczaj jest to najwy\u017cej kilka kilometr\u00f3w st\u0105d, na obszarach miejskich jest bli\u017cej. Dlatego te\u017c okre\u015blenie lokalizacji (geolokalizacji) jest stosunkowo dok\u0142adne.<\/p>\n

Ponadto dostawcy Internetu mog\u0105 \u015bledzi\u0107 strumie\u0144 danych ka\u017cdego klienta i widzie\u0107, co jest wyszukiwane w sieci, kt\u00f3re strony internetowe s\u0105 odwiedzane lub kt\u00f3re pliki s\u0105 pobierane. Jednak\u017ce, zgodnie z obowi\u0105zuj\u0105cymi przepisami, dostawcy us\u0142ug internetowych s\u0105 zobowi\u0105zani do usuni\u0119cia wszystkich danych historycznych na koniec sesji internetowej. Informacje o tym, do kt\u00f3rego adresu IP nale\u017cy dany klient, mog\u0105 by\u0107 r\u00f3wnie\u017c przechowywane przez okres maksymalnie siedmiu dni. W tym czasie mo\u017cna uzyska\u0107 nakaz s\u0105dowy, aby dowiedzie\u0107 si\u0119 o adresie zamieszkania i danych kontaktowych danego u\u017cytkownika. Jednak tylko w przypadku uzasadnionego podejrzenia, na przyk\u0142ad je\u015bli materia\u0142 chroniony prawem autorskim jest udost\u0119pniany za po\u015brednictwem platformy wymiany plik\u00f3w lub pobierana jest pornografia dzieci\u0119ca. Og\u00f3lnie rzecz bior\u0105c, klient zachowuje sw\u00f3j adres IP tylko na czas trwania sesji internetowej; nast\u0119pnym razem, gdy dzwoni, pojawia si\u0119 nowy adres IP. Dzi\u0119ki temu adres IP stale si\u0119 zmienia, jest on dynamicznie przydzielany przez dostawc\u0119 Internetu.<\/p>\n

Czy mo\u017cliwe jest ukrycie w\u0142asnego adresu IP?<\/h3>\n

Nie jest mo\u017cliwe ca\u0142kowite ukrycie w\u0142asnego adresu IP. Istniej\u0105 jednak programy takie jak JAP lub Tor, kt\u00f3re mog\u0105 by\u0107 u\u017cyte do ukrycia w\u0142asnej aktywno\u015bci w Internecie. Jednak korzystanie z takich us\u0142ug mo\u017ce spowolni\u0107 szybko\u015b\u0107 Internetu.<\/p>","protected":false},"excerpt":{"rendered":"
