Hi, I've had a cable modem for several months and the one thing I don't like is that I really don't seem to have the ability to change my I.P. unless I disconnect from the Modem for more than 3 days. I'm never off the Internet for more than 48 hours!
Is there a way to (Force) assign a new I.P.?
I'm using a Motorola Surfboard SB4100
Thanks,
__How to change I.P. ???

You don't have to buy a whole new NIC to change your IP address, this is done by either having it assigned by DHCP and you releasing/renewing the IP or setting a static IP in TCP/IP under network settings.Get a new NIC. Your IP will change.
If you are talking about MAC addresses then you would need to buy a new NIC. If you are assigned an IP by your ISP using DHCP then you can do the following:
- In Windows 9x go to Start | Run and type winipcfg. There will be 2 buttons release/renew.
- In Windows 2000 go to a command prompt and type ipconfig /release or ipconfig /renew

Thanks for the help guys, but Release/Renew doesn't get me a new I.P.
My ISP utilizes DHCP to assign the I.P's and rarely changes them even when the Lease's are renewed.
I saw somewhere that changing the System Time forces a I.P. change? That doesn't sound possible does it?
Any other ideas? For security (and) privacy, I would like to have the ability to freshen up my I.P. at will. I do use a Router and a software firewall also.

Dear God in heaven, please don't count on a new IP for security or privacy. Drop a few bucks and get a router that uses NAT for assigning a private IP to your PC and you will be much safer than trying to conceal yourself behind a floating IP address.
ISP's like to use DHCP for adressing so they can manage their nodes efficiently. When they see a node has reached a certain saturation point, they can change your address/gateway upon ,ease renewal and assign you to a less crowded node. For all you folks out there set up static, you may be damning yourself to a crowded node and costing yourself precious bandwidth.

Don't Worry Eddiec
I assure you that I'm not relying on a different I.P. alone for my security. I am in fact sitting behind a Router using NAT as well as a software firewall.
Thanks for the reply though.

Ooops
Sorry I missed the router and firewall at the end of your comment, bro. I get a little eye weary at the end of a long work day.
Most ISPs don't issue new IP's on request because they have to modify your account on a couple tiers. And then you'll usually have to change your host name, maybe only by a number or letter, but it still costs them support time, and as we all know, budgets are tight and they don't like to spend if they don't have to.

which company are you with?
My old internet provider (Shaw@Home) used to rotate IP address every few days or something like that but when Rogers@Home took over the area, I've had the same IP since.
Getting a new IP may do you no good. Who knows what the previous person did with the IP...

The MAC address and IP are not based upon each other. They are both needed for proper communication on a network but they are far from being based upon each other.the MAC address, since that is what the IP is based on (at least with my cable ISP).
A MAC address is a 48-bit hexadecimal number that is hard coded into your NIC and used at the Data-Link Layer of communications and is a flat addressing scheme.
An IP address is a 32-bit binary number that provides hierarchical addressing of nodes on a network, a MAC address does not provide this. IP addresses reside at the network layer of the OSI model (one layer above Data Link). Furthermore, an IP address provides information such as network, subnet and host....a MAC does not offer this, unless we are talking about IPX/SPX.
Every NIC has a unique address, where as IP addresses are finite. The 2 work hand in hand to provide proper routing through switches and router and also provide information to ARP and RARP requests. Your cable provider has routes in a table that refer your IP to your MAC address but that's about the extent of there relationship.
