what does it mean when a network admin says to use the first # in the address block of 226? And he gives me the below information:

IP’s: 204.68.134.226-.231
Mask: 255.255.255.0
GW: 204.68.134.254

Does it mean that I should use 204.68.134.227 to put into my computer?

1 Answer 1

With a 255.255.255.0 subnet mask, any address 204.68.134.1 - 204.68.134.254 are valid addresses, 204.68.134.0 will be the network address and 204.68.135.255 will be the broadcast address, so I'm guessing he means to use 204.68.134.226 although I would go back to him because if that's what he meant he should have just said so.

Edit: He may mean to check if any of the addresses in the range you specified are already in use, and if so to then use the next one.

I was thinking that he meant to use .227, but this would not be the case? –  Joe Jan 11 '12 at 20:15

@Joe Not with a mask of 255.255.255.0, no. –  Shane Madden Jan 11 '12 at 20:30
    
@Joe Why would you skip .226? –  David Schwartz Jan 11 '12 at 21:28

@Joe's admin is being obtuse and Joe made an innocent mistake. Joe is probably thinking of the rule "Don't use the first or last IP address in an IP range"‌​, but that rule doesn't apply to this scenario, since he has been allocated a subset of addresses within the 204.68.134.0/24 subnet. An easy mistake for someone who isn't a network administrator. The admin could have been more clear. –  Stefan Lasiewski Jan 11 '12 at 22:28
