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.
A 23-bit subnet mask in dotted decimal notation is represented as 255.255.254.0. This is derived from converting the first 23 bits to binary, which results in 11111111.11111111.11111110.00000000. When converted to decimal, the first two octets are 255, the third octet is 254, and the last octet is 0.
The dotted decimal representation of the IPv4 address 11001011.00000000.01110001.11010011 is obtained by converting each octet from binary to decimal. The binary octets convert as follows: 11001011 is 203, 00000000 is 0, 01110001 is 113, and 11010011 is 211. Therefore, the IPv4 address in dotted decimal format is 203.0.113.211.
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 term "slash notation" refers to the way a processor reads an IP address. The "Watchguard" website gives a table showing the most common network masks and their equivalent in slash notation.
