  • IP address range of class E?

    I have found that the address range of E class is from 240-255 in Cisco press text book and another text it is mentioned as 240-248. Which is correct?

    Thank you for consideration.

    Class D an E are not used for subnetting so normal rules do not apply

      Technically its 240-247 if you follow the pattern but since nothing beyond class D is used they just bundle it all as class E.
