Obtain Domain Name from DHCP

[Karsten Klinger]

Hi folks,

currently I try to obtain a FQDN for an Host via DHCP. At the specific item in DHCPv4 is the hostname and domain name configured. Unfortunately I got only the Hostname from DHCP but not the Domain Name.

OS: Ubuntu 20.04 LTS

I need the FQDN, because I need to update Windows DNS Server via SSSD.
