You are using Edimax, SMC or Digisol wi-fi extenders, access points, or bridges, there’s a chance that your is your The default gateway. Are you able to use it? Are you familiar with what type of address it is? You will find all the information you need about in this article. And not just that – you will also learn a thing or two about IP addressing and IP addresses in general.

Basics of IP addressing

IP protocols define all rules for IP addressing. This includes the form of an IP adress, as well the divisions and classifications, as well the rules for assigning IP addresses.

IPv4 is the protocol that is currently in use and will continue to be used for a long time (at least a decade or two). There’s also the IPv6 Protocol. This one is being developed for future use and is not yet completely operational.

Why do we need IP addresses?

Every house must have an unique address and street number. Each phone must have its own unique number. Imagine two houses sharing the same address, or three phones all having the exact same number. It would be chaos. The same reason that you need a unique number for your phone, every entity connected to any network also needs an unique IP address. That’s the only way to recognize that device, differentiate it from others, and communicate with it.

A device doesn’t exist on a network if it doesn’t have an IP address.

What is an IP address?

Each IP address as defined by IPv4 has both a binary form and a decimal form. A binary form is zeros and one. A decimal form are numbers. Our digital devices communicate in binary form. Decimal form is what we use to manage IP addresses.

Binary form is essentially a long string made up of zeros and ones. There are 32 bits total, which can be divided into four octets. Each octet is made up of eight segments.

You can convert every octet in a number between zero and 255 to get a decimal version. This is why this range exists. Eight zeros equal 0 and eight ones equal 255. Any combination of eight zeros or ones can give you a number that is between these minimum and maximum values.

The image below shows the address as it appears in binary and decimal forms. As you can see, it is a decimal form. Binary form is slightly more complex.

Close to 4.3 billion IPv4 addresses can be created by combing thirty-two bits. Seems a lot, but it’s actually insufficient. How insufficient? There are more than 10 million devices that can connect to the internet. Most of these devices connect to the internet every single day.

We needed to establish new rules and classifications in an effort to keep the IPv4 protocol working.

IP Address Classes

IPv4 addresses are broken down into five categories (5 scopes). These scopes of addresses do not have the same size. Addresses from different scopes can be used for different purposes.

The majority of available IP addresses are in the first three categories (A,B, and C). These addresses are used on networks (A – large networks, B – medium networks, C – small networks). These addresses are intended for multicast (D), and future purposes (E).

All IPv4 addresses are divided into 5 classes

All Class A, Class B, and Class C addresses are included. IANA allocates funds to 5 regional registriesThese regional registries allocate smaller addresses to different national and local internet portals.

This classification is essential because it defines each address class’ purpose and allows us know where the address is used. However, it doesn’t help us with our problem.

There is a difference between private and public addresses

If you look at the chart above, you’ll notice that there are three different types of IP addresses: one in Class A, one in Class B, and one in Class C. Private addresses are all addresses that belong to these scopes. All addresses that do not fall into one of these categories are considered open to the public. So, what exactly is the distinction between the two?

Private IP Addresses

Private addresses are only used on LANs and can’t be routed over the internet. These addresses cannot be used online, therefore they are not available for use on LANs.  What is a LAN? How do I get internet access?

LAN is an acronym for Local Area Network. A LAN is any closed network that connects all devices in one place. The best example of a LAN network is your home wi-fi network. Schools and offices also have LANs.

Every wi-fi enabled device on your network has a private IP address (phones. TVs. PCs. Laptops. Speakers. Routers. Extenders. These addresses are used to communicate with other devices in the same LAN. However, they cannot communicate with devices that are not part of your network.

Your router acts as a link between your devices and the internet. This device has a few roles – it is in charge of assigning IP addresses, it’s a mediator that enables the communication between devices connected to the same LAN, and it’s a mediator between your devices and the internet.

Every router includes a built in DHCP server. That’s a tool that holds a certain scope of IP addresses (aka DHCP pool) and gives/leases those addresses to devices connected to the router. This can be simplified by saying that every device connected to your wi-fi receives an IP address from your router.

Your router has two IP addresses – one private (aka default gateway) and one public. It is assigned both addresses by third parties. The manufacturer assigns one address and the internet provider gives the other. The first one can be used to communicate with your devices while the other is used to access the internet.

Your phone/PC sends a request (using private IP addresses) to your router. The router then uses your public IP address to locate the information you are looking for. It will send the information it finds from the internet to your phone/PC.

Private and Public IP Addresses

Router’s default IP address is usually the starting or ending address of some Subnet. Your router’s addresses to your devices come from the same subnet. Remember this – it’ll be important for our further discussion.

What is the Type of Address at

It is easy to see the IP class table and determine where this address belongs. It’s a Class-C address, and it belongs to a dedicated scope of private addresses within this class. can be a default IP address

Since it’s a Class-C private address, you know that it’s only used on LANs. can be a default IP address (it can be your router’s IP address or a default IP of some other piece of networking hardware). It can also be a client IP address – if it’s inside the DCHP pool of some router, it can be assigned to some device.

Is often used as a default gateway? Is this the default gateway for this address?

No, doesn’t get used that often. Manufacturers usually select starting and ending subnet addresses, as discussed above.,, Not because they are better in any way – it’s just because they are more convenient. Our address is second in the Subnet ( being the first).

Still, that doesn’t mean that is never used as a default gateway. You can check to see if this is your default address. Read our step-by-step guide.

What Devices Use As a Default Gateway

This address is used as the default gateway by a small number of devices. There are a few range extenders and access points available, as well as bridges from manufacturers such SMC, Digisol, and Edimax. Below are some examples of these devices.

SMC – SMC2555W-AG2 (AP), SMC2552W-G (AP), SMC2552W-G2 (AP), SMCWEB-N (AP)

Edimax – EW-7438RPn (range extender), CV-7428nS (bridge), WAP-1750 (AP), EW-7428HCn (AP), EW-7438RPn (range extender)

Digisol – DG-WR3001N (range extender),

How to Setup EW-7438RPn Range Extension

The majority of today’s wi-fi range extenders can be configured in one of two or three different methods. The most straightforward method is to use the WPS button on both your router and your extension. If your router doesn’t have a WPS button, you can use the default IP address and web configuration manager to set up the extender.

The default IP address for the Edimax EW7438RPn ( is It is possible to type it into the address bar of your browser and the Edimax login page opens. You can also type in http://edimaxext.setup. To log in, enter the default credentials – admin/1234.

The web configuration manager will open and display a list with available networks. Select yours, and then enter your network’s username and password. If you don’t see your network in the list, click Refresh and your wi-fi should appear.

The extender will connect to your wi fi network. Once connected, it will create a network and expand your network’s range.

Is used as a Client IP

It is feasible for a client’s IP address to be ours. Any private IP address can theoretically be used as a client address. To make a client IP, you’ll need a router with a different address in the same subnet. If the router’s default IP is, the first address in the DHCP pool will most likely be, which will be assigned to the first connected device. The default IP address for several Belkin routers (F9K1003, F9K1104, F9K1007) is If you have one of these routers, can be assigned to you.

It is possible to assign an address as either a static or dynamic Internet Protocol.

Dynamic IP

If dynamic IP is assigned to automatically, it will be called dynamic IP. Because the address is not permanently assigned to your device, we use dynamic IP. If the lease expires, the address could be returned to the pool.

Static IP

The address is considered static if you assign it to your device manually, either through your device’s settings or through a DHCP reservation. A static address is given to one device unless you manually change the settings.
