Difference between Dynamic and Static IP

Difference between Dynamic and Static IP

The major difference between dynamic and static IP is that dynamic IPs change every time one connects to the internet, while static IPs remain the same.

Internet Protocols, also known as IP addresses is a 32-bit number that is usually assigned to a computer when it connected to a network, such as the Internet. The IP address works similar to an actual address and lets computers know where to send data packets. The network devices use these address in order to communicate with each other.

The IP address are made up of 4 parts of numbers that are divided by dots (.) So, a typical IP address will looking something like – 72.169.189.01.

Although, the IP Based product / computers communicate with each other using IP addresses, to make it easier to remember the internet uses DNS or Domain Name System. This DNS is sort of an address book that pairs names to IP addresses. For example, if one wanted to visit the Google website, they would type in www.google.com in the address bar. The DNS will look up the IP address (74.125.239.35) paired with this name and will ping that address. Their system will respond back and the webpage will load on your computer.

There are two types of IPs – dynamic and static IP addresses. The major difference between dynamic and static IP is that dynamic IPs change every time one connects to the internet, while static IPs remain the same.

There are limited amount of IP addresses that are available and for this reason, many companies assign dynamic IPs, unless a static IP is asked for. So, every time a device is connected to the Internet, the IP address can change. This also allows the limited number of IPs to become reused, making it more convenient.

Broadband connections today lease IP addresses and use the DCHP dynamic IP address system. This system is also often considered safer, since the IP is always changing it makes it more difficult to hack the computer. Static IPs are commonly used by companies or people who require a similar IP address. The can apply for a static IP by paying a fee.

Comparison between Dynamic and Static IP:

	Dynamic IP	Static IP
Full form	Dynamic Internet Protocol	Static Internet Protocol
Definition	The internet protocol will constantly change	The internet protocol will remain the same
Cost Effective	More cost effective	Less cost effective
Security Risk	Lower	Higher
Upload/Download Speed	Slower	Faster
Good for	Good for residential user and small business owners	Web servers, email servers and other Internet servers. Also, for VOIP, VPN, playing online games or game hosting

Configure Router as Switch

How to configure router as switch?
Most likely you will ask this question if you plan to expand you home network, and you have only extra Ethernet router but not switch. At the same time you try to make use this extra router if possible without paying more on extra switch. Well… It’s pretty simple to get it done, keep on reading.

As you can see from 2 examples below, we can use second Ethernet router to expand existing wireless network or Ethernet home network, so that you can connect more computers to your network. Please note that first and second routers must be located on same network, because the second router just acts as a switch, not router anymore.

Ok. Let’s start to configure second router as switch.

1) Connect first router’s LAN port to second router’s LAN port by using a crossover cable. If one of the routers supports auto MDI/MDI-X feature, you can use either straight or crossover cable. Remember, don’t make any connection to second router’s WAN or Internet port.

2) Ok. Now assuming your first router's LAN IP is 192.168.1.1 with subnet mask 255.255.255.0, and then this will act as gateway for entire network (including the computers that connect to second router). If you would like to enable DHCP, then just enable the DHCP setting on first router and it will act as DHCP server for entire network (you don't need to enable DHCP on second router anymore). As an example, you can enable DHCP with IP range 192.168.1.2-250, subnet mask 255.255.255.0, gateway 192.168.1.1, DNS servers 208.67.222.222 and 208.67.220.220 on first router.

3) After talking about first router's configuration, proceed to log on to second router’s configuration page, then give this router an IP by configuring an IP and subnet mask under LAN setting. The IP that you configure should be located on subnet same with first router's subnet and this IP is not being used by any other device. If you have configured first router’s LAN IP and DHCP setting as shown in step 2 above, you can easily configure second router with LAN IP 192.168.1.251, 192.168.1.252 or 192.168.1.253 and subnet mask 255.255.255.0.

4) After that, don’t enable DHCP or any other settings on second router. If you have enabled DHCP or other settings, disable them. Finally SAVE all the settings. And now your have completed your mission of making second router as switch.

5) If you have computer that is configured to obtain IP automatically, connect it to other LAN port of this new "network switch", then it should be able connect to network, ping router IP and access to internet.
