Ipad renews 4500 times within 24h

Hi

 

 

Our logserver shows an Ipad renewing it's IP adress 4500 times within 1 day.

It's allowed this lease renew, and no errors are seen.

Has anyone seen this behavior from an Ipad before? What can be causing this ?

Hi Jan,

 

There have been several "issues" with Apple IOS devices in the past flooding networks with DHCP requests.

 

Here is one example:

I would suggest verifying if this ipad has an up-to-date version of IOS and also if there are any connectivity problems causing the DHCP requests.

 

Hope that helps!

Hi

 

Thank you.

I bellieve the IOS is a bit more recent than 4.0, but i will check into that.

I have been adviced to look into NTP-settings.
