#StackBounty: #networking #dns #dhcp Dynamic DNS updates via DHCP on CentOS

Bounty: 50

I’m running mostly Ubuntu VMs in an vSphere cluster where a VLAN is managed by a DHCP and a Windows DNS. From the Ubuntu VMs I can update the DNS records in the Windows DNS to point the dynamic IP to its hostname (set in /etc/hostname) with dhcp-identifier: mac addition in /etc/netplan/00-installer-config.yaml:

cat /etc/netplan/00-installer-config.yaml
# This is the network config written by 'subiquity'
      dhcp4: true
      dhcp-identifier: mac
  version: 2

But now I want to achieve the same DNS update functionality in a CentOS 7 VM, but can’t get it to work. Is it even possible?

Get this bounty!!!
