What Are Private IP Addresses?

IP or Internet Protocol addresses are numerical signs which can be assigned to every device attached to the internet. A device, it could be a computer or even a different computer which requires internet connection to operate properly, must have an IP address used on it in order to be able to access the net. There is a complete of 4294967296 or (2^32) IPs available, and the majority of the are public IPs. Public IPs are in reality those that directly access the net and are utilized by devices built online. IPs possess a format of x.x.x.x, where x equals all numbers between 0 and 255. Therefore, an example IP address is 67.23.121.5 or 173.21.234.112.

A relatively small number of IP numbers is available to private use. These reserved blocks are meant to be utilized by private networks and routers internally and they'll stop accustomed to access the net directly. There are several reserved blocks, however the most favored ones will be the 192.168.x.x and 10.x.x.x blocks. The former is widely utilized by many router manufacturers and is basically a standard today, while the latter isn't used anymore. In order to access a router's configuration panel, an individual IP number is used. For example, Cisco and Netgear routers utilize 192.168.1.1 IP number his or her default. Others manufacturers like Billion use 192.168.1.254. Some producers use 192.168.100.1 and 192.168.2.1.

The IPv4 strategy is the cornerstone of the internet as you may know it today. However, because of the boost in internet usage over the last ten years, we have run out of IP addresses. As of 2010, there isn't any more free available IPs. That means that they all are reserved and bought by various users (telecom companies, serves, governments). In order to overcome this problem, some other system called IPv6 is made and it is designed to solve this problem. IPv6 is an extremely advanced system which uses different nomenclature in comparison to IPv4 and possesses an overall total of 2^128, that is roughly 3.4x10^38. However, the switch between those two systems will need time, because it is a totally different system. However, once we switch onto IPv6, we can't be running out of addresses anytime soon, since there will probably not be enough devices to fill in the IPv6 quota.

Buyer's Guide: How To Choose A Wireless Router

How to choose the right wireless router for you

What is really a Wireless Router?

A wireless router can be a device that connects to your dwelling or office modem, so you may connect multiple devices, typically wired and wireless in your connection to the internet as well. Beyond the basic provision of wireless internet in your office or home, there are several functions that will be regarded when looking at buying a new wireless router. Please see below for common options that come with wireless routers, and study on for detailed explanations products those features are, and just how they may help you. See: How to Log Into A Comcast Xfinity Router Modem

Range

The array of a wireless router is really a measurement of how far (typically in feet) the signal of the router will travel. This measurement is normally determined in a very lab-type setting, to help you usually expect rather less range when setting one up in your office or house. Many different things will affect the selection of your router, in the physical placement near a wall or window, to interference using their company devices such as cordless phones or baby monitors. Most good wireless modems can handle broadcasting your signal to your selection of around 150 feet indoors, assuming typical household conditions.

Certain wireless routers like the D-Link DIR-655 are designed for signal range approximately 300 feet in your house, again - assuming perfect conditions. Range will also be afflicted with the kind of antenna the router uses to broadcast the wireless signal. For more information about how antenna design affects wireless signal, begin to see the antenna section below.

Single Band or Dual Band

When looking for a wireless router, you will run into two various sorts - single band and dual band. The 'band' may be the wireless frequency at which your wireless router outputs its' signal, and can either be 2.4 of 5GHz (Gigahertz). As you might have guessed, dual band routers will broadcast your wireless signal on both the two.4GHz and 5GHz bands, thus giving a better quality and quality signal.
Although a dual band router allows you more alternatives for delivering wireless signal in your house or office, the 5GHz signal frequency has some caveats. Firstly, the 5GHz frequency won't let your wireless internet signal travel as much as a 2.4GHz frequency signal will. Since most frequent household appliances don't operate inside 5GHz frequency range, you may come across less interference which can be nice, however you won't be capable to reap the benefits of that signal from too much away. 

The other downside to this, is not that all wireless devices are equipped for accepting a 5GHz wireless signal, so only a few device you use can take advantage from the added frequency.

If you've got a great deal of other wireless devices in your home, or live inside a crowded area, you will desire to pick a radio router with dual band. The added a higher level signal quality will assist you to deliver your wireless internet signal for a laptop or phone without getting confused with the rest with the signals moving through the airwaves. Picking a router which offers dual band technology is usually recommended - Although not every device will take advantage from the 5GHz band, having both bands broadcast means you can actually serve up a wireless signal regardless of the's connecting for your router.

A, B, G, N

Wireless signals come in the few different standards, known commonly as 802.11a, 802.11b, 802.11g, and 802.11n. As the letter gets higher, the signal quality increases, with n being the newest standard in wireless technology. Most new devices will probably be capable of connecting via 802.11n, nevertheless, you'll wish to make sure when establishing your wireless router that you could account for older devices you may have as well. Since some devices still utilize older but very popular 802.11g standard, you'll want to make certain you can broadcast both the new 802.11n signal, as well as the older 802.11g, and beyond.

802.11a - 802.11a can be an IEEE wireless networking standard that specifies a maximum data rate of 54Mbps with an operating frequency of 5GHz.   802.11b - 802.11b is an IEEE wireless networking standard that specifies a maximum data transfer useage rate of 11Mbps and an operating frequency of 2.4GHz.   802.11g - 802.11g is an IEEE wireless networking standard that specifies a maximum data transfer rate of 54Mbps plus an operating frequency of 2.4GHz.   802.11n - 802.11n is surely an IEEE wireless networking standard the specifies a maximum data transfer rate of approximately 540Mbps plus an utilizes MIMO (Multiple Input Multiple Output) technology to raise signal quality. 

Security

When you might be establishing a radio network at your office or home, you want to ensure you take your wireless security seriously. Picking a radio router that's capable of implementing the most popular security protocols will ensure that you can setup a safe and secure wireless network that won't leave you vulnerable.

The most frequent types of wireless security protocols are WEP, WPA, & WPA2. Each offers certain advantages, as well as a different type of passcode to permit access.

WEP

WEP (Wired Equivalent Privacy) can be a security protocol for wireless networks that may protect data via encryption over radio waves using point-to-point transmission. A pre-shared key (PSK), or passcode, is utilized allowing communication between your wireless router and also the endpoint (your personal pc).   

WPA

WPA (Wi-Fi Protected Access) resembles WEP, however WPA further protects your wireless data transmission via encryption. WPA works on the key just like WEP, but the benefit for using WPA over WEP is the key is automatically encrypted, making much more challenging for your passcode to get decoded.   WPA2 - WPA2 (Wi-Fi Protected Access 2) is similar to WPA, but geared toward people requiring the greatest amount of wireless security. WPA2 provides a much stronger encryption service by utilizing AES or Advanced Encryption Standard. 

Most wireless routers that you can buy offer WEP, WPA, and WPA2, with many routers adding additional levels of security. When it comes to keeping your wireless network secure, it'll come down in your implementation of security measures in addition than which router you choose to buy.

USB Functionality

Some wireless routers for example the Netgear WNDR4500 incorporate a USB port that will be used with regard to added functionality. You can tend to connect the Netgear WNDR4500's USB port to your USB thumb drive to simply share files on your network(also referred to as NAS - Network Attached Storage), and even connect a printer directly to the router, then access that printer wirelessly from any pc or laptop connected to your wireless network. Even if you lack an immediate requirement for this functionality at this time, if you're able to, look for a router that features a USB port onto it. Always future proof whenever you can!

Wired Ports

In addition to providing a wireless connection, most routers may also provide wired ports, so you may physically connect your local computer straight to the router. Computers that are physically connected for a router will manage to benefit from increased speed and reliability, so if you're capable of, it certainly is best if you get a router much like the Medialink Wireless N Router which has LAN ( or Local Area Network) ports so that you can can physically connect your pc for a router.

If you find a radio router without local network ports, ensure that it really is a router, and not just an access point. An access point is incredibly similar to a router, and might look similar, however the access point will simply provides wireless connection, and never the extra functionality needed to permit your pc to gain access to the internet wirelessly. If you already have a radio router in your office or home, you can utilize an access point to supply yet another method to obtain wireless, provided that most of your router provides basic routing functions to your home network

Antenna Design

When choosing a new wireless router, you desire to take into mind the sort of antenna design the router uses, which will either be internal or external. Aesthetically, a lot with the popular manufacturers are now choosing an internal antenna that's housed inside body in the wireless router.
While an internal antenna may look a bit 'cleaner' than using a small external mast type antenna sticking up through the the surface of your router, the external mast type antennas generally offer a better performance and range than the usual router with an inside antenna.

MIMO

MIMO (Multiple Input Multiple Output) is often a fairly new technology found in new routers which will ensure you get better speed and cover anything from your wireless router, by getting the wireless router to broadcast and receive multiple different signals immediately. To give a better idea products MIMO is and how it affects your wireless router's performance, imagine simply how much better highway traffic flows when you'll find five lanes for traffic rather than just one. This is the same principle that allows MIMO to increase a radio router's speed and performance.

IPv6

Since the web is expanding exponentially each day, the provision of unique addresses is rapidly drained, knowning that means at some time soon, we're going to have to start using IPv6 addresses. You needn't worry about the technical differences between IPv4 and IPv6 addresses, just take it easy and make sure that when you're going to purchase a new wireless router - make certain it supports IPv6.
