SUBNETTING VISUALIZER_
Drag the prefix and watch the 32 bits split into network and host in real time. Every value — mask, network, broadcast, host range, wildcard — updates as you move the line. The fastest way to see what a /26 actually means.
[ ▶ QUICK SUMMARY ]
An IPv4 address is 32 bits. The prefix length (e.g. /26) is how many of those bits are the network portion — the rest are host bits. This tool shows the split visually: drag the slider (or click a bit) to move the boundary and watch the subnet mask, network address (host bits all 0), broadcast address (host bits all 1), first/last usable host, host count (2^host-bits − 2), and wildcard mask recalculate live.
