Determine the differences between static and dynamic IP addresses to find out which can benefit you. An Internet Protocol (IP) address is a unique number assigned to every device on a network. Just as a street address determines where a letter should be delivered, an IP address identifies computers on the Internet. Network devices use
IP addresses to communicate with each other. The Internet uses DNS (Domain Name System) to enable people to use words instead of numbers for Internet addresses. You can think of DNS as an Internet address book, mapping domain names to IP addresses. When you type a URL into your browser, your browser looks up that domain name in DNS. For example, if you type When a device is assigned a static IP address, the address does not change. Most devices use dynamic IP addresses, which are assigned by the network when they connect and change over time. Most users don't need static IP addresses. Static IP addresses normally matter more when
external devices or websites need to remember your IP address. One example is VPN or other remote access solutions that trust (whitelists) certain IPs for security purposes. A static IP address is not required if you are hosting a server, although it can simplify the setup process. Google Fiber provides two options. Use advanced settings for your network to
configure dynamic DNS. When your IP address changes, the DNS entry for your server is automatically updated with its new IP address, so outside users can use the same domain name. You can choose the Dynamic DNS provider and don't have to install additional software on your computer. Use advanced settings to
reserve an IP address for a device on your local network. Your device keeps the same IP address until you cancel the reservation or remove the device from your network, even if the device is disconnected. When you sign up for Google Fiber
for small business, you can choose to have no static IPs (that is, dynamic IPs for all your devices), one static IP, or multiple static IPs. The number of static IPs available is shown on the screen when you sign up for service. If you sign up for static IPs, we will assign addresses to you when your service is installed and activated. If you're interested in Google Fiber for Small
Business, you can read more information about static IP addresses. If you are hosting your own server, review our accepted use policy. Was this helpful? How can we improve it? Anatomy of a Web address A Uniform Resource Locator, also referred to by its initials - URL -- is the unique address used to identify a Web site. It is similar to a home address, used to identify someone's mailing address. It is often simply called a Web address and is, literally, the address of a file on the Internet. Segments of a Web address The following example Web address is a Web page of the Internet Corporation for Assigned Names and Numbers (ICANN). ICANN is an international nonprofit corporation assigned responsibility for overseeing the management of the Internet's domain name system (DNS). http://www.icann.org/general/links.htm Here is the breakdown of components that make up this URL. http: The protocol or computer language a computer must "speak" in order to retrieve this file. It stands for Hypertext Transfer Protocol. You never need to type http:// to access a Web site, however in some browsers and operating systems, just typing the name of a URL (the second-level domain) without the top-level domain automatically launches a search. www: The name of the host computer. www is the most common, but you will occasionally see others, such as dir. icann: The second-level domain. The second-level domain in conjunction with the top-level domain makes up the domain name that corresponds to a specific address. org: The top-level domain. There are currently 13 top-level domains available. general: A directory, or folder, containing Web pages. links: The name of the file, or specific Web page, to be retrieved. htm: The extension of the file, similar to .doc, the extension used for Word documents. Most Web pages contain the suffixes .htm or .html, but other extensions are becoming increasingly common. Top level domains Here is a list of all top-level domain names now approved by ICANN. .com - commercial business .mil - U.S. military or affiliated agency .edu - educational institution (e.g., college) .net - large network .gov - U.S. governmental agency .org - U.S. nonprofit organization .biz - business .coop - nonprofit cooperative .info - any Web site .museum - museum .pro - professional (e.g., doctors, lawyers) .name - personal Web site .aero - airline For Web sites outside the United States, a two-character country code is used. For example, .ar is the code for Argentina, and .bt is the code for Bhutan. .us was not originally assigned to domain names in the United States, although it is often used to designate state and local government sites, including many public schools and libraries. Domains You need to be proficient with the domains in a Web address. For example, the Web site for the White House is www.whitehouse.gov; it has the .gov extension since it is a government institution. The Web address www.whitehouse.net leads to a hoax site that deliberately has the look and feel of an official U.S. government site. Guessing URLs If you can't find the home page of a well-known company or organization, try entering the name or abbreviation as the Web address. For example, the Web address for NASA is www.nasa.gov, the Nabisco Company's Web address is www.nabisco.com, and the Web address of the Bill & Melinda Gates Foundation is www.gatesfoundation.org. Beware of potential pitfalls inherent in this technique. Not all companies' Web sites correspond to their names. You need to evaluate very carefully the sites that you retrieve. For example, if you are looking for the Web site for the General Agreement on Tariffs and Trade (GATT), typing www.gatt.org will take you to a hoax site. The real Web address is www.wto.org. When in doubt, use a search engine to find and verify the correct Web site. What identifies the location of a page on the internet?The web address contains information about the location of the webpage. It is also known as the URL (uniform resource locator).
Which of the following top level domains is generally used by Internet service providers?As the internet continued to grow in use and popularity, dot-coms quickly became the most commonly used top-level domain. . net – Short for network, dot-nets were made for network technology companies like infrastructure companies or internet service providers (ISPs).
