Luettelo IP-osoitteista: 81.21.*.* (81.21.0.* - 81.21.255.*) | IP-osoite (Suomi) 🔍

Olet täällä

Tämä on luettelo IP-osoitteista, joissa ensimmäinen tavu on 81, toinen tavu on 21, kolmas tavu on välillä 0 - 255, neljättä tavua voidaan muuttaa (alapuolella oleva asteriski) Lista, joka ilmaistaan 81.21.*.* (81.21.0.0 - 81.21.255.255).

Tämä IP-osoitteiden luettelo sisältää 256 * 256 = 65 536 IP-osoitetta. Otetaan yksi IP-osoitteista 81.21.1.1 esimerkiksi tämän IP: n ominaisuuksien kuvaamiseksi:

Ensimmäinen IP-osoite esimerkki

Mutta tämä on vain esimerkki yhdestä IP-osoitteesta. Se ei tarkoita, että kaikilla tämän luettelon IP-osoitteilla olisi samat ominaisuudet. Jos sinun on tiedettävä muita IP-osoitteita ja tarkempia IP-osoitteita, napsauta otsikkolinkkiä.

IPv4: 81.21 Network Class, Net ID, Host ID

Kuvaus IP-osoitteesta binääri-, desimaali- ja heksadesimaalimuodossa Kuvaus IP-osoiteluokista A/B/C/D/E ja verkkotunnuksesta, isäntätunnuksesta

2. Luettelo luokan A IP-osoitteista

Luokan A IP-osoite tarkoittaa: IP-osoitteen neliosaisessa numerossa (esimerkiksi tavu 1.tavu 2.tavu 3.tavu 4) ensimmäinen osanumero (tavu 1) on verkon numero, loput kolme osaa numerot (tavu 2.byte 3.byte 4) ovat paikallisen tietokoneen numero.

Jos IP-osoite ilmaistaan binaarina, luokan A IP-osoite koostuu 1 tavun verkkoosoitteesta ja 3 tavun isäntäosoitteesta, ja verkkoosoitteen korkeimman bitin on oltava '0'.

Luokan A IP-osoitealue: 1.0.0.0 ~ 127.255.255.255, käytettävissä oleva IP-osoitealue: 1.0.0.1 ~ 127.255.255.254.

Verkkotunnisteen pituus luokan A IP-osoitteessa on 7 bittiä ja isäntätunnisteen pituus on 24 bittiä. Luokan A verkkoosoitteiden lukumäärä on suhteellisen pieni (2 ^ 7 - 2 = 126), jota voidaan käyttää yli 160 miljoonalle isäntäkoneelle suurissa verkoissa (2 ^ 24 - 2 = 16 777 214).
