IP addresses do expire. You cannot be guaranteed of obtaining that same IP address. Quote: |
DHCP provides three modes for allocating IP addresses. The best-known mode is dynamic, in which the client is provided a "lease" on an IP address for a period of time. Depending on the stability of the network, this could range from hours (a wireless network at an airport) to months (for desktops in a wired lab). At any time before the lease expires, the DHCP client can request renewal of the lease on the current IP address. A properly-functioning client will use the renewal mechanism to maintain the same IP address throughout its connection to a single network, otherwise it may risk losing its lease while still connected, thus disrupting network connectivity while it renegotiates with the server for its original or a new IP address.

It's been recommended that you keep track of which IPs each account has used.
eBay/PayPal have other ways of identifying that you are the owner of the account. They use cookies and flash cookies. If you use separate Windows user accounts for each eBay/PP account, you can keep the flash cookies in that Windows user account and they will not cross-contaminate other Windows user accounts.
