Somebody is smoking something.

Sorry, no duplicate MAC addresses.

They may be extremely similar. but NOT the same between any 2 or more devices.

Re: How to change MAC Address Ricoh MP 4054

Going to have to call BS on that. I could potentially see three devices with the same host name, but no manufacturer is ever going to let a duplicate MAC slip through QC, let alone three of them. That's a hardware level feature, not software.

sounds like someone did something with a bit of cloning somehow? maybe? but i agree no 3 the same...

Could have been a little of both. The computers were Compaq (before you laugh, their commercial stuff was pretty damn robust, unlike the home line) and Pfizer did have some issues, like authenticating against the least busy DC, which happened to be in Japan in the morning in Groton, CT. This was in the late 90's, early 2000's so high speed access was relative.

In the late 90's and early 200's computer registers not storing the entire MAC address wad definitely a probability.

Then that pharma company had a system that was not looking at entire MAC. Not a good idea. Either that or who ever was manufacturing the network cards was not following international standards and making cards with the same MAC hoping that they did not end up on the same network.

This is a false statement. Only the last 3 octets are unique, the first 3 are company and equipment identifiers. I worked for a company that serviced a large pharma company in Connecticut and we frequently had to move network cards to different network segments to fix this issue.

No two mac addresses are the same on the planet

Re: How to change MAC Address Ricoh MP 4054

I remember the early days of cable internet I had to purchase a cable modem from someplace like Best Buys and run a setup disk from the ISP. The setup disk obtained an IP address for your computer, created your account with ISP and recorded your computer's MAC either on your modem or with the ISP account. That one computer became the only thing that could connect to the internet through that cable modem. Later when I went to wireless, the first Linksys router with WiFi had one of its setup steps being cloning the MAC of your computer. In fact even the Cisco/Linksys E2500 that I am currently using has "MAC Address Clone" as one of the setup tabs. That is the only way I know of where 2 devices can appear to have the same MAC.

Now I have seen where the master browser has reported matching computer serial numbers when the serial numbers were too long and the master browser truncated them so the 5 computers purchased from the same vendor at the same time appeared to have the same number. I have also seen IP address conflicts on MFPs. I wonder if that is the actual overlap the original poster has?

Yes, 3 devices is same.

Why not if it's with pc i can do many of the same things. But this is the copier I totally lost.

3 devices with the same MAC address?

Yes, 3 devices is same.

Re: How to change MAC Address Ricoh MP 4054

I want to change it because I currently have 3 devices that are overlapping.

Thanks

On the MFP as kevslane writes it is not possible, on PCs you could use programs that mask the MAC and show another (Dark Web)
