Bad DHCP Addresses
Branden Watson
DIXON, SCOTT
We routinely get this as well – much more often with reservations. Since we had no way to track MAC addresses previously we did reservations on our Chromebooks so we could track filtering easier.
Because of the BAD_ADDRESSES – we ran a script that would delete the reservations each night and reload the range.
One of our techs thinks he found a pattern – it happens much more at some building and rarely if ever at others.
The building that has the most issues often have teachers that carelessly leave Chromebooks sitting open with the screen open when they go home at night. Even though they are asleep – we think it has an issue when we delete their reservation and recreate them.
Our buildings that properly close and store all their Chromebooks rarely have this issue.
This is only an observation that we have picked up on – no idea if there is anything to it yet. A closed Chromebook is also in sleep mode, so not sure why open vs closed would make a difference, but there appears to be a pattern.
We rarely have bad dhcp addresses when we do not use a reservation. We are using a mix of the original Samsung Series 5 and the newer Samsung Series 3 x303 models.
