Unknown DHCP request

Product Name: FX c5005d Docuprint
Operating System: Windows 7 x64

Hi All,

We have a Fuji Xerox c5005d Docuprint printer. It has been set up with manual IP address with IPv4 only. It has been working fine. However, our DHCP server randomly receives a series of DHCP request, all with the same MAC address (08:00:37:F4:XX:XX) which our DHCP server denies as it is not in its whitelist. Our server is isolated from the internet and there is no other Fuji Xero device on our network. There is only one network cable plugged into the printer.

Anyone else had this issue?

Cheers,

Vlad

Re: Unknown DHCP request

Disable IPv6 and make sure the DNS settings are not set to DHCP (they can be even when the IP is static)

Re: Unknown DHCP request

Hi Joe,

IPv6 was disabled but I just realised the IPv6 DNS was still set to auto. The thing is, the mystery MAC address is different to the one that is used by the active connection. There is no other connection from the printer to the network.

Cheers,

Vlad

Re: Unknown DHCP request

Since it isn't a Xerox device I really don't know, but printers have a MAC per connection, So Wired/Wireless/WiFi Direct etc all have a MAC of their own.

And Routers lie

Extenders are weird
