This is for all you Clone Modem MAC TRADERS [only takes 5 mins to read]
CABLE MODEM & UBR GATEWAY
Cloned modems can only work in a different segment of the cable network from the original cable modem
All Cable modems login to the cable network with there unique MAC address. Think of your town/ city as segmented like an orange. We all live in a certain segment and no two MAC addresses are the same. A cloned modem comes online, as long as it is in a different segment of the network from the original, it will work this is because the network primarily checks the cable modems MAC address and does NOT ALLOW 2 identical MAC’s to be online [registered on the network] in the same segment.
So when you are all requesting MAC’s for trade you should actually be asking for MAC’s from a different Cable network segment. You may think this obvious but the network does not necessarily follow the physical layout of your town/ city.
The segments of the cable network [like the orange are separated], in the case of cable the separation is done by ROUTER GATEWAYS, known as UBR’s [Universal Broadband Router].
FINDING YOUR UBR; is easy
The link given goes to the Grc [Gibson Research Corporation] website [a bit like who is]
https://www.grc.com/x/ne.dll?bh0bkyd2 <<< CLICK HERE
When you initiate the page it will return your full UBR address
xxx.xxx.xxx.xxx.cable.ubrxx.shef.blueyonder.co.uk
xxx is replacing actual numbers [you won't see xxx on the result]
The information address follows the following format:-
YOUR INTERNET I.P / NETWORK TYPE / UBR SEGMENT / YOUR CITY ACRONYM / PROVIDER DOMAIN NAME
For example if it returned a ‘UBR05’ this means your in segment 05 of your town/city
So for MAC trading purposes you need to trade with anyone outside UBR05, for example UBR01. Areas/ cities are normally segmented into approx 10 segments depending on size
You should supply TOWN/ CITY ACRONYM & UBR SEGMENT
ie SHEF.UBR05
All the Best viiiper
