i m trying to setup PXE using dnsmasq, it fails on "Address listen on port 53" but i don't see any IP address listen on this port

This IP 10.128.244.2 in the interface IP of the Infrastructure server where PXE is ported named as eno2

my dnsmasq.conf looks like this, All other setting are as per PXE configuration a default file under pxelinux.cfg

and a installer in default, and a user-data file under the /var/www/html

no-resolv
interface=eno2
listen-address=10.128.244.2
dhcp-range=10.128.244.102,10.128.244.110,6h
dhcp-boot=pxelinux/pxelinux.0
enable-tftp
tftp-root=/var/lib/tftpboot

Anyone having any idea on this error
