Which is correct? Thank you for consideration. OssianModerator May 16, 2009 at 1:16 am #178969 Re: IP address range of class E? Does this help: http://www.computerhope.com/jargon/i/ip.htm and http://en.wikipedia.org/wiki/Classful_network Class D an E are not used for subnetting so normal rules do not apply GarenMember May 17, 2009 at 11:03 pm #311766 Re: IP address range of class E? 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.
