Clients Devices Get Multiple Ip Adresses

[Mesut Muhammet Şahin]

Hi,

Our Dhcp servers are running with failover. We make relay for ip requests over network device to dhcp servers. (1 relay device and 2 dhcp server) We detect some mac addresses that have multiple ip addresses for same vlan.

I attached dhcp servers log in attachment for one mac address. How can clients get different ip addresses for same vlan?

# VLAN

subnet 100.64.0.0 netmask 255.255.224.0 {

  option routers 100.64.0.1;

  pool {

    failover peer "dhcp-failover";

    allow members of "dhcp-opt-82";

    default-lease-time 9000;

    min-lease-time 9000;

    max-lease-time 9000;

    range 100.64.0.41 100.64.31.250;

  }

}

Thanks in advance,
