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.
How it's working. A dynamically allocated IP address is an address made available to all registered users upon request. When you are configured to use DHCP, your machine sends a request to the DHCP server for an IP address each time it is booted. If your machine is registered, the DCHP server responds by providing an IP address and other configuration addresses such as Gateway and DNS.
When registering for a dynamic IP address, the address you receive from the DHCP server is taken from a pool of IP addresses. Each time your computer requests an IP address from the DHCP server, it will be allocated an available address from the dynamic address pool. This address may be different each time your computer is started or if you release and renew your current IP address.
What is an dynamic IP address (for begginers)?
Requesting DHCP computers receive a dynamic IP address (think temporary phone number) for the duration of that Internet session or for some other specified amount of time. Once the user disconnects from the Internet, their dynamic IP address goes back into the IP address pool so it can be assigned to another user. Even if the user reconnects immediately, odds are they will not be assigned the same IP address from the pool. To keep our telephone telephone analogy going, using a dynamic IP address is similar to using a pay phone. Unless there is a reason to receive a call, the user does not care what number he or she is calling from. There are times, however, when users who connect to the Internet using dynamic IP wish to allow other computers to locate them.
Virtual IP address
Virtual IP address (VIP or VIPA) is an IP address that is not connected to a specific computer or network interface card (NIC) on a computer. Incoming packets are sent to the VIP address, but all packets travel through real network interfaces. VIPs are mostly used for connection redundancy; a VIP address may still be available if a computer or NIC fails because an alternative computer or NIC replies to connections.
Sticky dynamic IP address
A sticky dynamic IP address or sticky IP is a term created by cable and DSL users to describe a dynamically assigned IP address that does not change often. This is however an informal term, as a sticky IP does not differ in any way from other dynamic IP address. Even though IP addresses may not change often for cable or DSL users, the addresses are still controlled by the standard DHCP process. Since the modems are often online for extended periods of time, the leases on the IP addresses are commonly renewed, and therefore may not change.
Port number, ip address, computer name
Right click mycomputer/properties will give you most info about your computer or control panel, system icon .not sure what port # you are refering to.
Ip address .type winipconfg in start/run i think will work ,I haven't used win98 for a couple of yrs now .
winipcfg" is the correct spelling, but yes- that will give you all of your IP configuration info.
In terms of your question about the port #, you would have to clarify that by giving us more specific information. Network applications and/or services all use different ports, but that info isn't anything you usually have to configure or worry about.
What i am doing is writing a simple socket program using c++ to connect to another pc. The socket properties requires a port number and computer name to connect to that particular pc. Thus this what i am trying to find out is how to get the other pc's port number and computer name

How do I hide my IP address?
The most common method to hide your IP address is to use a proxy server in one form or another. A proxy server is a computer that offers a computer network service to allow clients to make indirect network connections to other network services. A client connects to the proxy server and then requests a connection, file, or other resource available on a different server. The proxy provides the resource either by connecting to the specified server or by serving it from a cache. In some cases, the proxy may alter the client's request or the server's response for various purposes.
There are several implementations of proxy servers that you can use to hide your IP address (in an attempt to remain anonymous on the internet):
Website Based Proxy Servers
A Website based proxy server is a website that provides a form for you to enter the URL of a website that you wish to anonymously visit. When you submit the form the website proxy server makes a request for the page that you want to visit. The machine usually does not identify itself as a proxy server and does not pass along your IP address in the request for the page. The features of these sites vary (ad blocking, javascript blocking, etc) as does their price. Some are free and some charge. Examples of website proxy services are:
Proxify.com
Browser Configured Proxy Servers
There are also stand alone proxy servers that allow for you to configure your browser to route your browser traffic through that machine, which then makes a request for a page on your behalf, and then sends you the results. These are usually used at no cost to the user. Since they are accessible to the public these are often quite slow. Please see instructions for using a proxy server.
There are a variety of types of these proxy servers:
Transparent Proxy
This type of proxy server identifies itself as a proxy server and also makes the original IP address available through the http headers. These are generally used for their ability to cache websites and do not effectively provide any anonymity to those who use them. However, the use of a transparent proxy will get you around simple IP bans. They are transparent in the terms that your IP address is exposed, not transparent in the terms that you do not know that you are using it (your system is not specifically configured to use it.) This type of proxy server does not hide your IP address.
Anonymous Proxy
This type of proxy server identifies itself as a proxy server, but does not make the original IP address available. This type of proxy server is detectable, but provides reasonable anonymity for most users. This type of proxy server will hide your IP address.
Distorting Proxy
This type of proxy server identifies itself as a proxy server, but make an incorrect original IP address available through the http headers. This type of proxy server will hide your IP address.
High Anonymity Proxy
This type of proxy server does not identify itself as a proxy server and does not make available the original IP address. This type of proxy server will hide your IP address.
Installed Software Proxy Servers
There are a variety of companies and software packages available at either a onetime cost or at an annual subscription. These are usually faster and more reliable than the above proxy servers. Some of these services would include:
Hide My IP
Anonymizer.com's Anonymous Surfing
GhostSurf 2007 Platinum
TOR (Read about TOR)
VPN Services
A virtual private network (VPN) protects your data and identity over public networks, like the Internet and wireless hotspots. Various protocols are used to create an encrypted tunnel that transports data securely. While a firewall may protect the data on your computer, a VPN will protect your data on the Internet. The goal of a VPN is to implement the same level of security provided by private networks at substantially lower costs. VPN services provide different gateway cities where the IP address assigned to your computer is located. This allows users to access websites only available to users from a certain country. This application is particularly important for travelers who need to access websites from their home country and for people living in regions rife with censorship, like China and Iran.

Finding Your IP Address and a Website's IP Address
Nowadays, we live in the world of the internet and rarely does a single day pass by in which we don't log onto the net. However, have you ever thought of how we are able to connect to a person sitting nearly on the other side of the globe? In the case of the internet, the network on which all the systems reside is called WWW and it's too complicated for a non-technical person like us to comprehend it fully. So, I will just state briefly how different computers talk to each other on this world wide web or any other smaller network like you use at your work place or in your home.
