The MAC is just a random, long, "serial" number in essence that each
manufacturer applies to their device as it is produced. It's kind of
"burned" into the device hardware BIOS code. (Although most devices of
that type will allow for MAC spoofing where you can tell the device what
MAC address to respond with. But you can't have two devices, with the
same MAC, connected to the same cable drop...won't work.)
How the manufacturers keep from having duplicates is, as far as I know,
due to the length and randomness of the number...or maybe they're
assigned number ranges. I dunno.

Yeah - Forgot about the MAC address thing. I'm not fully versed in
what the MAC address is all about - but, I do know of it - and shoulda
figured that it would be related to my question. Totally makes sense -
and I'm pretty sure you are absolutely right - that even though U have
Cox - that my Cablevision would operate the Same way - and not allow a
2nd MAC address for the same house - unless it was Paid for and done
thru them!
Bummer...

Most cable internet companies, unless you are paying extra for a
static IP address, track your device MAC address and only permit one
(which they record and check at each connection) MAC address at a time.
So, yes, you can purchase your own (make sure it is compatible) cable
modem box, but it is likely you won't be able to connect both at the
same time. Usually, if for any reason the cable modem has to be
changed, you have to call the cable companies tech support and have
them re-set (initialize) the MAC address they have recorded, so that
when you connect your new device they record the new MAC.
Of course, your cable company may not work that way. My experience is
with Cox and Cable One.

Hey folks,
I just moved into the downstairs appt. of a buddy of mine. He has
Cablevision in the house here - for his TV, Net & Ph. service. And,
in this downstairs appt. he has a cable box.
My problem is that I want a Wired Net access - and right now folks
in this appt were just jumping onto his Wifi.
The Cable co. happened to call me a litle while ago - to check on my
satisfaction - and so I asked them if my buddy got a 2nd cable Modem
box - what's the charge. Its basically the same as Just ordering
Internet alone - at $49/mo.!
As such - my Q. Is it possible to get a Cable Modem box at like a
Radio Shack - which I could just hook up to the Cable wire to get my
own Wired Net access? And - if so - is it possible that the Cable
co. would later find out???
And - while my buddy was on Tech Support for this Surveillance Video
camera (his bus. is alarm systems) - the guy claimed that maybe he
should get a 2nd IP address for his house - to possibly alleviate a
bottleneck in bandwidth. I wasn't sure about this -but, figured
someone on here would know what that Tech guy was talking about.
Thanks in Advance!
Kurt
