Who owns a IP Addresses?

By mmiller ·
In 1996, my company got a Domain Name with an IP Address. Now, 5 years later my ISP is dropping the company that supports my Internet wire coming into the building. I am having a new DSL wire bought into the building and I am keeping my original ISP. The ISP has informed me that I can not have the same IP address that I used to have and they will issue me a new IP address. This old IP address was a class C with 254 routable IP's. Do they have the right to take this IP address from me or doI have the legal rights to it?

Who owns a IP Addresses?

There used to be a time when you could purchase IP addresses directly from the Internic. However, because of the limitations of the IP addressing scheme as well as the difficulties or routing disparate networks, it has long been that only ISPs canpurchase IP addresses in blocks, and they then 'rent' these addresses out to their subscribers.

It is very likely that this is the case with you, and therefore you have essentially no recourse but to accept the change.

Even if it turns out that your company did purchase the IP network directly from the Internic, there are almost insurmountable routing problems with trying to use your own IP address range in a DSL environment.

It will be far, far easier to give in and use the new IPs that they wish to assign you. As long as they change your required DNS entries to reflect the new addressing, you shouldn't suffer too much for this.

Hope this helps.

The Internic is in charge of issuing IP addresses.
If you are using a firewall (and you should be) or a gateway then you don't really care what you use for your internal addresses so long as you don't use a block that is commonly used on the internet. In this way your router will direct all traffic not on your net out to the internet. In most cases you will only need one IP address to appear to the outside world, that of your firewall/gateway and this is the one supplied by your ISP. As far as this address goes you don't really care so long as your domain registration reflects this number so that internet traffic can find you (email etc.)by way of your DNS entry.
The otherside of your firewall/gateway will have an address in common with your internal network
