Show / Find DHCP Lease Time

I'm just wondering of a terminal command or any way to see my ip dhcp info: when it was obtained, when it expires, etc.

Thanks.

The DHCP lease time is configured in your router. Consult the router's user manual on how to configure its settings.

Indeed. But I was wondering if there is a way to see this information strictly from the client.

Thanks.

You may look for a third-party utility that may provide the information, but it's not available through the Network preferences. I tried the Network Utility but it did not provide that information either.

Yea, I should have stated I looked in those places too. I'm thinking with so much unix code there has to be a terminal command. I tried the man page of ifconfig but didn't see anything.

Hi Brad

You will find DHCP client lease information in an appropriately named interface file in the /var/db/dhcpclient/leases directory.

Within the file will be the LeaseLength key and the value (in seconds), i.e. 86400 = one day.

I hope that helps.

Dominic.
