R7000 MAX Address Reservation

I have 3 R7000 and 2 of which are currently in access point mode.

 

The R7000 can only store 64 reserved addresses before it says Maximum Number of Reserved Address Reached. 

Would it be possible for a bios update to increase this number?

Pretty sure some of the hacked firmwares can have more reservations...

 

Could more than 1 router be set as a DHCP server so can have 64 reservations on each?

 

Thanks in advance Chris.

Rasberry Pi would handle this easily. It could also so be used as DNS server and also have Pi Hole for controlling browsing sites. Rasberry Pi's are cheap and run well for me. Have one doing DNS and Pi Hole currently.

   It's not a BIOS, it's the firmware.  And sure -- all you need to do
is persuade Netgear to change the limit.

   Then use one of those?  Or buy a more capable router?

 

   Why do you need so many reserved addresses?  What are the devices?
Do they all really need fixed (reserved dynamic or static) addresses?
If so, then can you configure some of them with static addresses,
instead?

   Generally, no.  Running multiple (uncoordinated) DHCP servers on one
LAN segment/subnet is asking for trouble.  For example, consider a case
with two DHCP servers, where one has an IP address reservation for a
particular MAC address, and the other doesn't.  The client device
broadcasts its (DHCPDISCOVER) request, which is received by both DHCP
servers.  One DHCP server responds with the desired reserved address,
and the other responds with an address from its DHCP address pool.  Who
wins that race?

 

   In principle, you could use some external (wire-connected, I'd
advise) gizmo as your (one, only) DHCP server.  Perhaps a Raspberry Pi?
