Traditional MAC addresses are 12-digit (6 bytes or 48 bits) hexadecimal numbers. The illustrated code given below shows how to generate a UUID for a given host, identified by its MAC address, using the uuid1 () function. Getnode () can be used to extract the MAC address of the computer. One way to represent them is to form six pairs of the characters separated with a hyphen (-) or colon(:). A valid MAC address must satisfy the following conditions: It must contain 12 hexadecimal digits. Combine all four digits to make one binary number.Given a string str, the task is to check whether the given string is valid MAC address or not by using Regular Expression.Next, convert each decimal digit into binary, making sure to write four digits for each value.

Convert each hex value into its decimal equivalent.

Split the hex number into individual values.

In this example, extra 0s are added at the highest values to create two groups of four bits.

Convert each decimal value into its hex equivalent.īreak into groups of four - 0011 0011.

Next, convert each group of four digits into decimal.

If there are less than four digits, use just that number of digits for that group.

Start at the rightmost digit and break the binary number up into groups of four digits.

If the decimal number is smaller than 16, take the hexadecimal equivalent of the decimal number.Įxample - convert decimal 22 to hexadecimalġ6 goes into 22 once with 6 left over, so 22 ÷ 16 = 1 remainder 6.Take the hexadecimal equivalent of the remainder - this represents the second digit. Take the hexadecimal equivalent of this result - this represents the first digit. If the decimal number is bigger than 16, divide it by 16.The AQA specification requires you to be able to convert from decimal to numbers containing multiple digits in hexadecimal.
