Still working out every subnet by hand? Practice until the math feels automatic. Network Labs & Subnet Prep gives you a new subnetting question every time, with the steps written out after you answer. It also includes independently created practice questions and guided offline labs for CCNA 200-301 study. SUBNETTING DRILL • A new question every time, so you practice the method instead of memorizing answers • Core skills: network address, broadcast address, usable host range, usable host count, prefix to mask, and mask to prefix • Advanced: wildcard masks for ACLs and OSPF, same-subnet checks, sizing a subnet for a host count (VLSM), splitting a network into subnets, and route summarization • Answers come from the built-in subnet calculator, which is tested against an independent reference ALSO INCLUDED • Subnet calculator: network, broadcast, host range, mask, wildcard mask, and usable hosts for any IPv4 address and prefix length • Practice questions by exam topic, with an explanation for every choice • Quick 10 and a mini mock exam • Guided labs for CLI, routing decisions, VLANs, ACLs, NAT, STP, and packet flow • Progress by exam version, with readiness shown as a study indicator, not a pass guarantee • Study Mode: lock the apps you choose for a set time, free for everyone • No account, no ads, and no data sent to external servers FREE AND LIFETIME ACCESS Free: all six core drill types without limits, one question of each advanced drill type, 50 practice questions, 25 guided labs, Quick 10 and Mini Mock, explanations, progress tracking, and purchase restoration.
