Qeexidda Maskaxda ee Tusaalaha iyo Tusaalooyinka
Maaskaro maskaxeed waa cinwaanka IP- sida loo qoondeeyey xajmiga hoose ee shabakada kombiyuutarka ama qalabka shabakada kale. Waa nambarka 32-ka ah oo u kala qaybiya cinwaanka IP-ka qaybihiisa labadaba: Cinwaanka shabakadda iyo cinwaanka martigelinta.
Maaskaro yar-yar (oo sidoo kale loo yaqaan netmask), ka dibna, waxaa loo qaabeeyey sidan:
Maaskaro yar-yar ayaa la abuuraa adoo dejinaya dhamaan xuduudaha shabakadaha 1s iyo xayirada martigelinta ee 0s. Shabakadda waxay kaydineysaa laba cinwaan oo aan loo qoondeeyn karin marti-gelinta, iyo kuwa ay ku jiraan 0 cinwaanka shabakadda iyo 255 cinwaanka war-baahinta.
Tusaalooyinka Subnet Maskada
Kuwani waa netmasks loo isticmaalo fasalka A (16-bit), heerka B (16-bit), iyo Class C (24-bit):
- Shabakadaha A ayaa taageeraya 16,777,216 martigaliya oo leh maaskaro hoose ee 255.0.0.0.
- Nidaamyada fasalka B waxay leeyihiin maaskaro yar oo ah 255.255.0.0 waxayna leeyihiin 65,534 qalab IP keliya.
- Inta badan shabakadaha guryaha waa Class C, oo loogu talagalay maaskarada subnet 255.255.255.0. Qiyaasta cabbirkan waxay ku jiri kartaa ilaa 256 qalabka IP, meelo badan oo guryo caadi ah ama ganacsi yar.
Tixgeli cinwaanka IP-ga 128.71.216.118. Haddii aynu u maleyno inay tahay cinwaanka Class B, labada nambar ee ugu horeeya (128.71) waxay sharxi doonaan cinwaanka nambarka B-da halka labadii ugu dambeysay (216.118) ay tilmaamayaan cinwaanka martida.
