Frequently Asked Questions
Why convert IP formats?
Different systems use different representations. Network engineers need decimal, binary, or hex formats for subnetting and debugging.
IPv4 to IPv6?
IPv4 can be embedded in IPv6 using ::ffff:a.b.c.d (IPv4-mapped) or ::a.b.c.d (IPv4-compatible).
IP in binary?
An IPv4 like 192.168.1.1 is 11000000.10101000.00000001.00000001 in binary (32 bits total).
How do I convert an IP address to a decimal number?
Multiply each octet by its positional value: first octet x 16777216, second x 65536, third x 256, fourth x 1, then sum them. For example, 192.168.1.1 = 3232235777.
What is an IP address in hexadecimal format used for?
Hexadecimal IP format is used in programming, network packet analysis, and URL obfuscation. For example, 192.168.1.1 becomes 0xC0A80101 in hex.
IP 地址格式說明
點分十進位：最常見的 IPv4 表示法，由四個 0-255 的數字組成，用點分隔。例如：192.168.1.1
十進位整數：將 IP 視為一個 32 位元無符號整數。192.168.1.1 = 3232235777
十六進位：以 16 進位表示的 IP。192.168.1.1 = 0xC0A80101
二進位：以 2 進位表示的 32 位元 IP。用於理解子網遮罩和 CIDR。
