 # Subnet Calculator
 
+With the **Subnet Calculator** you can [calculate a subnet](#calculator), [split subnets](#subnetting) and create a [wide subnet](#wide-subnet). Both IPv4 and IPv6 are supported.
+
 ## Calculator
 
+On the **Calculator** tab, you can calculate a subnet by entering the IP address and the subnet mask. The subnet mask can be entered in CIDR notation.
+
+Possible inputs:
+
+- `10.0.0.0/16`
+- `192.168.0.0/255.255.255.0`
+- `2001:db8::/32`
+

 ## Subnetting
 
+On the **Subnetting** tab, you can split a subnet into smaller subnets. The subnet mask can be entered in CIDR notation.
+
+Possible inputs:
+
+| Subnet                      | New subnet mask   |
+| --------------------------- | ----------------- |
+| `10.0.0.0/16`               | `/18`             |
+| `192.168.0.0/255.255.255.0` | `255.255.255.128` |
+| `2001:db8::/32`             | `/48`             |
+

 ## Wide Subnet
 
+On the **Wide Subnet** tab, you can create a wide subnet that includes both given subnets. The subnet mask can be entered in CIDR notation.
+
+Possible inputs:
+
+| Subnet 1                    | Subnet 2         |
+| --------------------------- | ---------------- |
+| `10.0.0.0/16`               | `10.2.0.0/16`    |

+
+{: .note}
+IPv6 is not supported.
