Disclaimer: This information is provided to help you configure your system so that you can use hotComm, IM-Live, and ezPeer. We strongly advise that you consult with your network and router administrators before making any changes. Note: in a network configuration, the internal IP is not the same as the IP assigned by your ISP. When you are opening ports to allow incoming connections to your computer, your computer must be assigned a static internal IP address, to ensure that the incoming connections always go to the correct computer.
Choose an IP address, and collect other information needed in order to assign a static IP address to your computer.
In your router administration program, find an IP address that can be assigned as a static IP. Must not be one that has been assigned to another device (often these are the low numbers). In Use the following DNS server addresses, enter all the IP addressses for the DNS servers your router uses. TweetNot many users are aware that Windows 7 provides more than one way to configure a workstation’s network adaptor IP address or force it to obtain an IP address from a DHCP server. In order to successfully change the IP address via Command Prompt, Windows 7 requires the user to have administrative rights. At the Administrative Command Prompt, type netsh interface ip show config, which will display the network adapters available on your system and their names. In our example, we’ll be modifying the IP address of the interface named Wireless Network Connection, which is our laptop’s wireless network card.
Even if the Wireless Network Connection is set to be configured via DHCP, we can still configure a static IP address. This command forces the DNS server setting without any validation and therefor no error will be presented at the CLI output in case the DNS server is not reachable.
This article showed how to configure a Windows 7 network interface with an IP address, Gateway and DNS server, using the Administrative Command Prompt. When you have changed the DNS successfully, you can check the network speed by clicking on "Test Network Speed" button.

The acronym “IP”, in computing terminology, refers to an “Internet Protocol address.” It is number that identifies your computer or network and separates it from all other computers or networks on the Internet. A number of different things can potentially happen to your business if your system’s IP addresses are compromised. In addition, certain websites may install malicious software on your computer that uses your IP address to glean additional information.
Peer Block is one program capable of protecting your computer’s IP address by blocking specific connection attempts.
BeeThink IP Blocker is another program available for Windows that operates similar to Peer Block.
You can also use most standard firewall software, like the program that comes natively installed in the Windows operating system, to block specific IP addresses or entire ranges of addresses. While the most popular method is configuring the properties of your network adaptor via the Network and Sharing Center, the less popular and unknown way for most users is using the netsh Command Prompt. This means even if you are not the administrator, you must know the administrative password, since you will be required to use the administrative command prompt. In the search dialog box that appears, type cmd and right-click on the cmd search result displayed. Note down the name of the network adaptor for which you would like to set the static IP address. We also showed how to set a Windows 7 network interface to obtain an IP address automatically from a DHCP server. How to change back to the original DNS In case you don't want to use custom DNS anymore, please check on "DHCP" then click on Apply button. It allows other computers and networks to identify your own connection and initiate communication, which is the basis of how the Internet actually operates. Because of its importance and the precise way in which it operates, someone with questionable intentions could use the IP address to gain access to your network from the outside. This information could be small, like what websites you browse to be used for targeted advertisement purposes. This, however, requires you to know the specific IP addresses that you are trying to block and input that information manually.

Likewise, computers on a network have IP addresses, unique to each of them, to identify themselves and communicate with each other.
Because of the important job of an IP address, it is equally important that you take steps to protect your own, especially if you own and operate a business. Peer Block operates using a series of IP address “block lists,” similar to the virus definitions that your business anti-virus software would use. In addition to offering “block list” protection from IP addresses, the program is also capable of preventing specific types of attacks from outside sources.
Windows Firewall in particular does not have block list capabilities that rival that of other programs.
If your IP address is used in the wrong way by a person with malicious intentions, it could potentially cause irreparable harm to your network, your computer or even your business. Someone with advanced technical knowledge could also potentially use your business’ IP address to hide their own, covering their own tracks while performing illegal activities and pinning the blame on you and your company. Protecting your IP address not only protects your business, but it protects your clients as well. If any of the IP addresses on the block lists (which are typically malicious programs, computers and users) attempt to make connection with your business computer, the connection is denied. It is, however, already installed on your computer so no additional downloads are required. If your business server experiences a DDoS attack, the server itself is overloaded with so many simultaneous information requests that it can no longer function. This can be especially useful if your business computers have been compromised, and malicious software is attempting to make contact with its original source.
