0xC0

0xC0 is a hexadecimal literal representing the value 192 in decimal. The 0x prefix denotes hexadecimal notation in many programming languages, so 0xC0 equals 192. In binary, 0xC0 is 11000000.

In character encoding, 0xC0 is outside the standard 7-bit ASCII range. In ISO/IEC 8859-1 (Latin-1) and Windows-1252, the byte 0xC0 maps to the character À (A with grave). In Unicode, the code point U+00C0 corresponds to this character. In UTF-8, the character À is encoded as two bytes: C3 80. The single leading byte 0xC0 by itself is not a valid first byte in modern UTF-8; sequences starting with C0 or C1 are disallowed to prevent overlong encodings.

In IPv4 networking, the numeric value 0xC0 equals the first octet 192. Address blocks beginning with 192.x.x.x include the historical Class C range (192.0.0.0 to 223.255.255.255). Private networks frequently use 192.168.x.x as part of the private IPv4 address space.

In programming, 0xC0 is a common hex literal across languages such as C, C++, Java, and Python; it is used in constants, bitmasks, and low-level data processing, and can also appear in contexts involving color components or protocol values.

Overall, 0xC0 is a multi-context value with meanings tied to its numeric value, encoding mappings, and practical use in software and networks.
