FAQ (Frequently Ask Questions)

What is Reverse IP

In computer networking, reverse DNS lookup or reverse DNS resolution (rDNS) is the determination of a domain name that is associated with a given IP address using the Domain Name System (DNS) of the Internet. Computer networks use the Domain Name System to determine the IP address associated with a domain name. This process is also known as forward DNS resolution. Reverse DNS lookup is the inverse process, the resolution of an IP address to its designated domain name.

What is IP Address:

IP address (Internet Protocol address) is a unique number that devices use to identify and communicate with each other on a network using the standard Internet protocol. Any participating device including the routers, computers, time servers, printers, Internet fax machines, and some phone should have its own unique address. This allows the information is now sent the names to indicate where to send the next, and the recipient of information on who the intended destination. The IP address will consist of four parts from to 255,255,255,255, but some of these values are reserved for specific purposes.

IPv4 Address:

IPv4 addresses are usually represented in dot-decimal notation (four numbers, each ranging from 0 to 255, separated by dots, e.g. Each part represents 8 bits of the address, and is therefore called an octet. It is possible, although less common, to write IPv4 addresses in binary or hexadecimal. When converting, each octet is treated as a separate number.

IPv6 Address:

The rapid exhaustion of IPv4 address space, despite conservation techniques, prompted the Internet Engineering Task Force (IETF) to explore new technologies to expand the Internet's addressing capability. The permanent solution was deemed to be a redesign of the Internet Protocol itself. This next generation of the Internet Protocol, aimed to replace IPv4 on the Internet, was eventually named Internet Protocol Version 6 (IPv6)[3] The address size was increased from 32 to 128 bits (16 bytes), which, even with a generous assignment of network blocks, is deemed sufficient for the foreseeable future. The new design is not based on the goal to provide a sufficient quantity of addresses alone, but rather to allow efficient aggregation of subnet routing prefixes to occur at routing nodes.

IP Versions

There are two versions of the Internet Protocol (IP): IP version 4 and IP version 6. Each version defines an IP address differently. Because of its prevalence, the generic term IP address typically still refers to the addresses defined by IPv4. The gap in version sequence between IPv4 and IPv6 resulted from the assignment of number 5 to the experimental Internet Stream Protocol in 1979, which was never referred to as IPv5.

What Is Longitude?

Longitude is the geographic coordinate most commonly used in cartography and global navigation for east-west measurement. A line of longitude is a north-south meridian and half of a great circle.

What Is Latitude?

Latitude gives the location of a place on Earth north or south of the equator. Lines of Latitude are the horizontal lines shown running east-to-west on maps. Technically, latitude is an angular measurement in degrees ranging from 0° at the equator to 90° at the poles. The complementary angle of a latitude is called the colatitude.

What Is Designated Market Area?

A Designated Market Area (DMA) is a group of counties in the United States that are covered by a specific group of television stations. The term was coined by Nielsen Media Research, and they control the trademark on it. There are 210 DMAs in the United States.

What Is Area code?

Area code - necessary (for the most part) only when dialed from outside the code area, from mobile phones, and (especially within North America) from within overlay plans. Area codes usually indicate geographical areas within one country that are covered by perhaps hundreds of telephone exchanges. It must usually be preceded in the dial string by either the national access code or the international access code and country code. For non-geographical numbers, as well as mobile telephones outside of the United States and Canada, the "area code" does not correlate to a particular geographic area.

What Is ZIP code or Postal Code?

The ZIP code or Postal Code is the system of postal codes used by the United States Postal Service (USPS). The letters ZIP, an acronym for Zone Improvement Plan, are properly written in capital letters and were chosen to suggest that the mail travels more efficiently, and therefore more quickly, when senders use the code. The basic format consists of five numerical digits. An extended ZIP + 4 code includes the five digits of the ZIP code, a hyphen, and four more digits that determine a more precise location than the ZIP code alone. The term ZIP Code was originally registered as a servicemark (a type of trademark) by the U.S. Postal Service, but its registration has since expired.

Changing your Internet IP address

When connecting to the Internet over a dial-up Modem, your ISP will assign your computer an address each time you connect. This means that often each time you connect you'll have a different IP address. If you're wanting to change your IP address, try disconnecting and reconnecting. If you're assigned the same address, disconnect for a few minutes and then reconncect.

Broadband service providers will assign your computer or home network a static IP address. If you're connected to a broadband network and need to change your IP address try following the steps below.

Getting a new IP address may be as simple as disconnecting the power to your broadband modem. Disconnect the power from the modem and leave it disconnected for a few minutes. If you have a network router connected to the modem, we also suggest disconnecting the power to the router.

If disconnecting the power to the modem and router did not work it may still be saved in your router configuration. Try releasing and renewing the Internet IP Address for the router. Steps on how to do this can vary depending on the router. However, is often done through the Status or setup in the router setup.

If the above two suggestions do not work, disconnect the power to the modem and router (if applicable) and leave them disconnected overnight or for as long as possible.

Finally, if all of the above suggestions still prevent you from changing your IP address it's possible the ISP may have a long lease settings that prevents a new IP address from being assigned unless it is abandoned for days. In this situation, its usually easiest to contact the ISP to get the IP address changed.
