About IP Address Converter
An IPv4 address is a single 32-bit number; the familiar dotted form is just four bytes written separately. 192.168.1.10 and 3232235786 are the same address, which is why databases and log formats often store the integer instead.
The binary column is where subnetting becomes obvious - the network part is the leading bits that a mask keeps. For working out masks and host ranges, the IP Subnet Calculator does that directly.
