printer installation with DHCP constant on

Re: printer installation with DHCP constant on

Put simply: when your computer gets an IP from DHCP, it also reports to the internal DNS servers to say that hostname X now has IP address Y.
Your local machine also caches some DNS records for easy recall, and then checks back to the DNS server at a regular interval (usually around 90 minutes) for any changes to that cached copy.

I observed this in real time the other day when rthonpm was walking me through setting up DNS/DHCP in Windows Server 2019.


To put another way,

Pointer records are registered to DNS by the DHCP Server

-- Host Names are registered to DNS by the DHCP Client


** This is due to the DHCP Client being the source of the host name
*** and the DHCP Server is the source of IP addresses

But will this setup allow vpn printer requests (f.i. printing from home)? And scanning, you didn't mention that part either ...

That's an entirely separate issue from anything discussed here. It all depends on how the firewall rules between the VPN and the onsite network are configured. If using a print server in the office, as long as SMB traffic can go between the VPN segment and the regular network printing will work. For scanning, I'm guessing you have someone scanning to a workstation on VPN? It's still SMB for that so you'd still just need inbound and outbound access for TCP 443.
