Because 209.165.201.3 is the last IP address in the network 209.165.201.0/30 and thus is the broadcast address, it is not available for use as a host inside the network.

With a 255.255.255.252 subnet mask, the ip address you are specifying is the broadcast address

BROADCAST=209.165.201.3
NETWORK=209.165.201.0

You will only be able to use 209.165.201.1 or 209.165.201.2 as an IP address.
