The largest hex number that can be represented in bytes depends on the number of bytes being considered. Since one byte consists of 8 bits, the maximum value for one byte is 255 in decimal, which is represented as FF in hexadecimal. For multiple bytes, the largest hex number is determined by the number of bytes times 2 (since each byte is represented by two hex characters). For example, for 4 bytes, the largest hex number is FFFFFFFF.
255
If the byte represents a signed number, values commonly go from minus 128 to plus 127. If the byte represents an unsigned number, values commonly go from 0 to 255.
An IPv4 address represented in dotted decimal notation consists of four octets, each ranging from 0 to 255. Each octet is 1 byte, so the total size of an IPv4 address is 4 bytes. Thus, an IPv4 address in dotted decimal notation is 4 bytes in size.
There is basically one way to write hexadecimal numbers. Of course, the numbers represent information, and this information can be represented in may other ways; some of them are in binary (4 binary digits for each hexadecimal digit), in decimal, or each byte as as decimal number (as in the dotted decimal notation used for IP version 4 numbers).
The biggest number that can be represented in one byte is 11111111. Binary numbers have the ability to added together in a fashion similar to decimal numbers.

The address of the last byte in a 512 mega byte memory, expressed as a decimal number, is 536,870,911.
255
Nobody knows what you are talking about, but if you mean what the biggest number is in a byte, it is 255 or 127. The former is only for unsigned, while the latter is the maximun if the byte is signed. If you mean how many numbers can be represented, it is 256 or 128. Again, the former is if it is unsigned and the latter is if it is signed.
The byte 00001000 represents the decimal number 8. In binary, each bit represents a power of 2, starting from the rightmost bit, which is 2^0. In this case, the byte has a '1' in the 2^3 position (8), and '0's in all other positions, resulting in the total value of 8.
The term used to describe smallest possible element in computer memory is byte. Some people may say bit. But logically, that's incorrect. Each character is represented by 8 bits or 1 byte. In Unicode it is represented by 16 bits or 2 bytes.
A byte represented of 8 bits
If the byte represents a signed number, values commonly go from minus 128 to plus 127. If the byte represents an unsigned number, values commonly go from 0 to 255.
An IPv4 address represented in dotted decimal notation consists of four octets, each ranging from 0 to 255. Each octet is 1 byte, so the total size of an IPv4 address is 4 bytes. Thus, an IPv4 address in dotted decimal notation is 4 bytes in size.
255 is the largest decimal number. 1 byte (8 bits) can store 256 *values* (0-255).
