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:


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

With a subnet mask, any address - are valid addresses, will be the network address and will be the broadcast address, so I'm guessing he means to use 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, 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 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
