- jlgaddis 7y ago> 254 addresses. 2 ^ (32 - 24) == 256
- dlgeek 7y agoThere are 2 reserved addresses in a /24 that can't be used - https://en.wikipedia.org/wiki/IPv4#Addresses_ending_in_0_or_255 https://en.wikipedia.org/wiki/IPv4#Addresses_ending_in_0_or_...
- asdfaoeu 7y agoWhile that's true you still pay for them and there are some circumstances where they would be used.
- oarsinsync 7y agoThose addresses are reserved if you subnet the /24 as a /24. You can use them if you use the IPs either as /32s or /31s. Some platforms may choke on this. I have no issues personally with .0 and .255 used on my network as routable host addresses.

- jlgaddis 7y agoI'm a network engineer. IPs ending in .0 and .255 CAN be used and quite commonly are. (I appreciate the downvotes from the clueless who don't know this, however.)
