is there a script that can be installed to run every four hours to clear leases that have lease age of say 35 minutes? However, Pi-Hole has a built-in DHCP server: Configure your router’s DHCP options to force clients to use Pi-hole as their DNS server. If your router doesn’t let you change these settings, you can use Pi-hole’s built in DHCP server to achieve the same effect. Just not seeing it. DHCP leases are just an additional layer for my (family members/devices) presence detection. You can specify multiple subnets here. "The Pi-hole® is a DNS sinkhole that protects your devices from unwanted content" Each time the lease is renewed (which happens automatically), there's a chance the device will receive a different IP address. On top of that every user of the free service is required to accept terms and conditions of service, which includes and clearly state that their device mac address and other identifiable information , such as device name may get logged for purposes of legitimate interests to provide this free service and that bandwidth wasting ads and malicious and bad content sites will get filtered. It worked pretty well. # DONT RUN ANY OF THIS ON YOUR PIHOLE, run it on the effected device if you can. Press question mark to learn the rest of the keyboard shortcuts. 5. If you are familiar with dnsmasq (or are willing to familiarise yourself with it), you can configure it in any way that's supported by dnsmasq, unless it would conflict with Pi-hole's own settings. This removes an active lease from the server. Note, however, that the clients also actively need to ask for a new lease (reconnection, restart) as it may otherwise continue to use its old (even if now invalid) configuration until the lease time expires. Unfortunately, Pi-hole cannot do anything about this. Edited Jul 29, 2015 at 07:41 UTC Thanks. Try adding the lease, running sudo service pihole-FTL restart and then reconnect your device. max-lease-time: Maximum number of seconds allowed for a lease.

Since I cannot setup Pi hole as DNS server on ISP modem, I need to set up dhcp server on Pi-hole. No new dynamic IP leases were being issued. They’re independent. I don't think anything else will work reliably. Depending on the jurisdiction in your country of residence, you could be obliged to gather and archive consent of your users prior to joining your WiFi (and this may well be true even regardless of Pi-hole's usage). Luckily for me Pi-hole has it’s own DHCP server, so I made the choice to disable the DHCP server of my router and to use the DHCP server of Pi-hole: DHCP settings of Pi-hole. Next, a little bit of IP management is in order. A few months ago, I decided to setup PiHole on a Raspberry Pi to block ads across all devices on my network. Ansible is a simple, but powerful, server and configuration management tool. Learn to use Ansible effectively, whether you manage one server--or thousands.

Under the hood, Pi-hole's embedded dnsmasq is handling DHCP. but I cannot specify a wider range than /24 as ISP modem (Bell Canada) does not allow and first two octets are set in firmware to be 192.168 and mask is also set to /24. Powered by Discourse, best viewed with JavaScript enabled. Lease time: 6 hrs. I’ll check my ARP table and DHCP lease tables for my PiHole, locating it at 192.168.85.244. At any rate, understanding the potential pitfalls, I'll only look out for ADD messages to detect presence (and use other means to detect absence). I think it’s time to try using the Pi-Hole’s DHCP function. Like a lease on a car or apartment, a DHCP IP address lease has a fixed duration, and before it expires the lease must be renewed. The IP Address is reserved for that device until the reservation expires. Assign 192.168.1.171 to Raspberry Pi Pi-hole 1 (primary), and … First I was planning to use ISP router as dhcp and then change the DNS server to the Pi-hole IP address, but found that ISP modem will only allow Public IP as custom DNS servers. Once a DHCP server has handed a lease to a client, it doesn't track whether that client still has an active conection. I can confirm that above solution works, you can go into /etc/dnsmasq.d and then edit the file 02-pihole-dhcp.conf, the config line something along the line "dhcp-range=192.168.2.11,192.168.2.250,20m" and then restart the pi or "service pihole-FTL restart". This book is a printed edition of the Special Issue "Security and Privacy in Wireless and Mobile Networks" that was published in Future Internet Advantages: Simple, easy, and fast setup.

For computers and other network devices, to communicate on a network they need a unique IP Address. Thanks to this book, every Raspberry Pi owner can understand how the computer works and how to access all of its hardware and software capabilities. iOS allows the DHCP lease to expire, but continues using the IP address after that time. If you like my posts, please send me a donation to provide you also in the future with ad-free information.

Pi-hole's DHCP server tries to be deterministic, i.e., it always tries to assign the same IP to the same device (in contrast to enumerating them in the order of their appearance). Since you mention receiving "old" messages, it seems you are using dnsmasq's dhcp-script option to get informed of DHCP lease information. If I'd correctly assume you are using dhcp-script, then what you observe would be expected for a restart: dnsmasq is informing you of its known leases. wlan0 # This command releases the client's current DHCP lease.
