We can’t, there is no such thing IPv6 addresses are 128 bit and hexadecimal, IPv4 has 32 bit decimal addresses.

Typo: “The first nibble will be 8 + 4 = 12. The decimal value 7 is C in hexadecimal.”

Hi Rene,

“In the decimal system we count from 1-10, in the hexadecimal system we count from 1 – F”

should be “decimal 0-9, hexadecimal 0-F”
