FAQ
How is a dotted decimal IPv4 mapped to a 32-bit integer?
Each octet represents 8 bits: (Octet1 * 256^3) + (Octet2 * 256^2) + (Octet3 * 256) + Octet4, yielding the 32-bit decimal integer.
Can integer or hex format IPs be entered in browser URLs?
Yes. Most modern operating systems and web browsers resolve integer or hex representations directly to their target hosts.
Does the converter classify private vs public address ranges?
Yes. It automatically identifies Class A/B/C networks, RFC 1918 private subnets, loopback addresses, and multicast ranges.
