How can I read Domain Name from DHCP offer

I want to use domain name. and we use IP address from DHCP server.

How can I get domain name from DHCP offer?

We are using NET+OS 7.4.1


Domain name is issued by DNS server, not DHCP server.
you have to assign a domain name in DNS for a particular IP.
so next time when you access the domain name DNS server willr esolve the IP and you will be able to access your device.
