== == Dynamic IP addresses are most frequently assigned on LANs and broadband networks by Dynamic Host Configuration Protocol (DHCP) servers. They are used because it avoids the administrative burden of assigning specific static addresses to each device on a network. It also allows many devices to share limited address space on a network if only some of them will be online at a particular time. In most current desktop operating systems, dynamic IP configuration is enabled by default so that a user does not need to manually enter any settings to connect to a network with a DHCP server. DHCP is not the only technology used to assigning dynamic IP addresses. Dialup and some broadband networks use dynamic address features of the Point-to-Point Protocol. source: http://en.wikipedia.org/wiki/IP_address

A Dynamic Server serves up IP addresses to computers on a network. The purpose of the dynamic server is to protect the user's identity online. This is why it sends different IP addresses every time the user logs on.
Yes, you can track your IP address by using a dynamic DNS service (the ones I’ve used are free).
DHCP (Dynamic Host Configuration Protocol) assigns IP Addresses & other DHCP Options to Clients.
Seems like you could use a free dynamic IP solution (like ZoneEdit) to give your server a constant name (even though it has a dynamic IP address), then run Bind on your server. Unfortunately, though, the top-level name servers probably cache the IP addresses of other name servers, so it might not work for a while after your IP address changes. Anybody know if this is the case?
Dynamic Host Configuration Protocol (DHCP) A protocol that provides a means to dynamically allocate IP addresses to computers on a local area network. The system administrator assigns a range of IP addresses to DHCP and each client computer on the LAN has its TCP/IP software configured to request an IP address from the DHCP server. The request and grant process uses a lease concept with a controllable time period.
