What is my WAN side subnet?
The public side of a router is visible on the Internet. The public side is also referred to as the WAN or Wide Area Network side of the router. The range of allowable LAN side IP addresses is called a subnet (as in sub-network, as in, only use these few numbers of all the billions of possible numbers).
How many subnets does a WAN have?
Step 4 – VLSM and subnetting a subnet For the WAN links, we need at least three subnets. Each must have a minimum of two usable IP addresses.
Can LAN and WAN have same subnet?
At a minimum, hosts on the LAN will be able to reach either the WAN subnet, or hosts on the LAN which are in the WAN range. (you could try adding a static route, for example.) But never both. Also, WAN hosts will not be able to reach LAN hosts in the same IP range.
Is WAN IP same as Gateway?
WAN IP: 216.119. 143. xx -an address the world sees for you when you browse the web. Gateway IP is the WAN address dedicated to the modem (like 216.119.
What is my router WAN IP?
The Wide Area Network (WAN) IP address of your router is the address supplied by your Internet Service Provider (ISP). Your router’s WAN IP address can be check in the router’s web-based setup page.
What is difference between subnet and WAN?
When the LANs are joined, you often don’t extend a LAN subnet all the way through that physical or virtual wire until it gets to the other LAN subnet. Instead, you use another subnet to represent the connective area between the two LANs. That is your WAN.
How do you calculate subnets?
Total number of subnets: Using the subnet mask 255.255. 255.248, number value 248 (11111000) indicates that 5 bits are used to identify the subnet. To find the total number of subnets available simply raise 2 to the power of 5 (2^5) and you will find that the result is 32 subnets.
What is WAN IP and LAN IP?
To conserve the addresses, IPv4 is available at two levels: Wide Area Network (WAN) and Local Area Network (LAN). At the WAN — or Internet — level, the address is always unique at any given time. Generally, each website has a WAN IP address.
Should router and modem be on same subnet?
By default, the cable modem router acts as a Dynamic Host Configuration Protocol (DHCP) server. These addresses must be part of the same IP address subnet as the cable modem router’s LAN IP address. Using the default addressing scheme, define a range between 192.168. 0.2 and 192.168.
What is WAN IP on router?
A WAN address is the IP address that your router uses to connect to the Internet. It is different from IP addresses of computers and devices on a local network, because the WAN IP is essentially shared by all the devices. There are many uses for a WAN address, and the address is easy to find out.
How do I find my WAN port number?
How to find your port number on Windows
- Type “Cmd” in the search box.
- Open Command Prompt.
- Enter the “netstat -a” command to see your port numbers.
