Hexadecimal question explanation

damien2008

Can someone please explain which of these hex numbers is the lowest

• 0010.7bcc.733a
• 0010.7bcc.7347

Thanks in advance !

733a is the lowest.

Because 733a in decimal - 29498
And that 7347 in decimal - 29511

Hex = base 16, where 1-9 = 1-9, A=10, B=11, C=12, D=13, E=14, F=15, 10=16.....

Thanks for the reply

Each hex number is 4 digits right ?
So 733a

7 = 0111
3 = 0011
3 = 0011
A = 1010

Can you explain how you get the decimal equivalent ? ( 29498 )

733A
0111001100111010

2^1 = 2
2^3 = 8
2^4 = 16
2^5 = 32
2^8 = 256
2^9 = 512
2^12 =4096
2^13 = 8192
2^14 = 16384

Adding them all together = 29498

Can you convert 00111010 to an ipv4 octet? If yes, follow the same logic!

See attached pic, think the penny's dropped........

The confusing bit is seeing HEX letters, you instinctively convert to decimal, as in hex A = 10
With 733A the A does equal 10, but with 73A3 the A would be binary positions 128 and 32

This was most helpful..Large scale Hex was never covered in most of my materials. Thus my question

thanks
