And honestly why the hell do they need to connect my service to my Mac address, with my former DSL provider and when I hade comcast years ago there was none of this crap. How does it help the ISP, I don't understand. |

Decatur, IL | Unless I am missing something, if a cable modem is set up to only give one valid IP, what does the MAC number matter.
One paid for IP, then one issued, no matter what was requesting it. |

Possibly, I have no doubt there is a reason. I just don't understand why I did not have to do that with Comcast or my past DSL ISP, must be something different in the system design, frustrating none the less. |

| Again someone can correct me if I'm wrong. But I know in the past Comcast used the same system that Insight used. A check of their forum here would confirm this. So I would assume Comcast users at one time must have been locked down my MAC address as well.

I have an inside source at insight, since I use to work for the tech support. Glad I left by the way! Anywho, they are going to a new system called Sams. I think it is the self provisioning system that comcast currently uses. I know they have the system setup in Indianna and maybe some in Illinois but not sure. |

Also if you need an additional ip address, then the other mac address is registered. The cable modem does not give out the address, a DHCP server that checks the SAS or SAMS database releases a routable or non-routable ip address based on the entry in the database. No entry, no routable ip address. This is also true if you wish to have 2 cable modems on an account.
The reason a mac address was not needed your DSL is most DSL providers connection is based a Username and Password, not on a mac address. Also, most DSL modems are also routers, which only needs one routeable ip address. This DSL portion is from my own personal experience and helping others in my area, so if I am not correct on anything please don't think I am misleading, this is from my own experience. Hope this helps on your understanding with why a mac address is needed. |

| I would venture to say that the biggest reason a MAC is needed on cable is that it acts like a username/pw since there is none for cable systems. In effect, it prevents theft of service; If a cable modem whose MAC isn't registered with Insight tries to acquire a public IP on the network, it is denied. This way your neighbor can't hook up on your line with a cable modem he bought and steal internet. Comcast does do this actually and so does every cable system because they must have that MAC address in order to properly provision your connection.
also, most DSL modems aren't routers.. (they aren't even modems technically.. since they aren't taking analog signal and making it into digital.. they take a digital signal and bridge it to your ethernet card). most DSL 'modems' are simply bridges. And DSL modems with router type services are more like a bridge with a switch attached internally (whether it be 1 port or 4 or whatever.) Some DSL modems these days are a little smarter than that and actually have a PPPoE client built in to them, so they wouldn't qualify as just a bridge. |

Decatur, IL | Doesn't the cable modem itself have a MAC? I would think the if the cable modem has a MAC, and configured for the purchased IP, then it should not matter what is connected to the ethernet port. |

Technically a modem has nothing to do with analog or digital necessarily. It means modulator-demodulator. It converts one signal type to another. They might both be analog (like in a voice relay system), they might both be digital (like in DSL), or it may be both (like a dial-up data connection.

I was refering to the case of dial-up modem where analog singnal on the line is convered into digital at either end for the computer/network.. but yes you are right ... technically ;p Either way, most DSL 'modems' are just dumb bridges

Decatur, IL | Unless Insight changed recently, they require MACs on both modem and ethernet devices. It is what is connected to the modem, I don't understand why they need the MAC |
