It lists prefix lengths using slash notation with corresponding total address counts, usable host counts, subnet length, and subnet masks. It also summarizes classful IPv4 ranges (Class A–E), private IPv4 blocks, and special-purpose addresses such as local host, APIPA, and bogon ranges. Additional guidance covers how a subnet is created by dividing the host identifier into subnet, network, and host portions.",{"@graph":63,"@context":119},[64,80,102],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":11,"@type":70,"position":76},"https://docshare.wps.com/template/presentations/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/subnetting-cheat-sheet/571401/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/subnetting-cheat-sheet/571401.png","ImageObject",442,249,{"name":88,"@type":89},"Miles","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-10-22","2026-10-13",true,{"@type":98,"interactionType":99,"userInteractionCount":101},"InteractionCounter",{"@type":100},"ViewAction",6,{"@type":103,"mainEntity":104},"FAQPage",[105,111,115],{"name":106,"@type":107,"acceptedAnswer":108},"What does CIDR prefix length mean in the cheat sheet?","Question",{"text":109,"@type":110},"The cheat sheet uses slash notation (e.g., /24) to indicate the subnet prefix length.
