Unable to make static IP address on one subnet
Currently I am unable to make one IP as static, but if I make it from DHCP it works.
When I make IP as static and start network service then it shows the following error,
Error, some other host already uses address 10.58.190.100
I have total 4 NIC interfaces and all static, but only i am getting this error on 10.58.190.X network.
Please help me in this regard

Re: Unable to make static IP address on one subnet
If the addresses in your subnet are controlled by the DHCP server, the right ways to make a static IP are either:
1.) exclude that IP from the pool of allocatable addresses on the DHCP server
(so the DHCP server won't care about that address at all)
or
2.) specify a permanent MAC address <-> IP mapping for the static address on the DHCP server
(with a permanent IP reservation configured, the DHCP server should not care if it's used unannounced, as long as the system using the IP has the correct MAC address)
Once either 1) or 2) is done, it should be possible to configure the IP address as static.

Re: Unable to make static IP address on one subnet
Currently I am having this issue in all machines which is in 10.58.190.x VLAN.
In my DHCP Server i have all these machine entries with MAC address rserved and when I try from DHCP it is allocating IP and working fine.
But when I make IP as static then it throws the following error,
Error, some other host already uses address 10.58.190.XXX

Re: Unable to make static IP address on one subnet
I have attached the error screenshot as well.
Please find the machine details in the DHCP server.
subnet 10.58.190.0 netmask 255.255.255.0 {
interface eth2;
option routers 10.58.190.1;
option subnet-mask 255.255.255.0;
option broadcast-address 10.58.190.255;
option domain-name-servers 10.58.131.246;
}
group {
filename "pxelinux.0";
next-server 10.58.190.199;
host panaji {
