Interesting. 400 people share two IP addresses? Does that mean if 2 of those people are already online, the other 398 must wait their turn? |

Easy, dynamic versus static IP addresses. Static IP addresses don't change and dynamic do. Also, people are able to change a MAC without changing any hardware. |

However, with a firewall, thousands of people appear to share a single ip. For example, 57.68.138.5, from SITA-Societe Internationale de Telecommunications Aeronautiques, a company in France. This is the firewall ip that we use at work. Every employee at my company and several other companies will appear to be using this same ip. With this type of setup, internal ip's of the form 10.xx.xx.xx are used, but all are mapped to the same external ip 57.68.138.5. Cox Cable offers a simlar firewall service, but it's mostly used for commercial sites, similar to my company. |

Cox uses static ip addresses. At least they're supposed to be.
Sometimes it changes, but normally I get the same ip every time I power on my system. Are you claiming that a person can change the MAC of a cable modem without changing any hardware? I'm not aware of any ethernet devices that let you change the MAC, as this would create a potential collision with another device. I have a Toshiba PCX2600, are you claiming there's a hack to change the MAC of this cable modem? If you replace the NIC or motherboard getting a new MAC there, it doesn't change your ip at Cox, since it's assigned by the software downloaded by Cox Cable into your cable modem. Your ip probably changes if you replace the cable modem, but this requires calling into Cox, giving them your new Cable Modem's MAC, so they can download the controlling software into it. |

Do they actually state that everyone gets a static IP or does it cost extra? With Comcast, my dynamic IP doesn't normally change. The lease gets renewed every couple of days or so, at least I think that's how it goes... > > Are you claiming that a person can change the MAC of a cable modem > without changing any hardware?

If you look at the headers for this message and an earlier one, my IP should be different now. > If you replace the NIC or motherboard getting a new MAC there, it > doesn't change your ip at Cox, since it's assigned by the software > downloaded by Cox Cable into your cable modem. Have you actually tried anything to see if this is true or not? |

I use onboard ethernet controllers. I upgraded from a D850GBAL to a D875PBZ based system which obviously had a different MAC than the old system, and the ip remained the same. I upgraded cable modems (from 10mbs half duplex to 100mbs full duplex), and had to call into Cox Cable to tell then the new MAC before the new cable modem would work. I don't remember if the ip changed or not. I have two computers at home. Originally, I used a router, and the two computers shared a single ip. Cox supports up to 4 computers this way, all sharing the same ip (just like the firewall setup at my company). I then upgraded to having two ip's, one per computer (for old online games). I had to replace the router with switcher, and then have Cox enable the seperate ip service. You can up to 3 ip's on 3 computers max. When I made this change, the two new ip's were different than the old single ip. Regardless of how I plug into the computers, or which one is powered on first, each computer always seems to get the same ip. So maybe now it's following the motheborard's NIC MAC now. I don't know how to change the MAC, seems like this would be a bad idea since it would create a potential conflict between 2 ethernet devices. Still if there's a way, I'm curious. |

> > Oops, there it changes again. I can do this too, but I do it the old fashion way, by going to a friends house (just down the street), or to work and posting from there. Look at my post at 3:07 pm today, I went to France and back to California in just a few hours. As I posted before, it's my company's ISP. That French company was one of the first internet providers and is pretty popular. |
