+# IP Checker
+
+The ```ip``` checker checks if the value is an IP address. If the value is not an IP address, the checker will return the ```NOT_IP``` result. Here is an example:
+
+```golang
+type Request struct {
+  RemoteIp string `checkers:"ip"`
+}
+
+request := &Request{
+  RemoteIp: "192.168.1.1",
+}
+
+_, valid := Check(request)
+if !valid {
+  // Send the mistakes back to the user
+}
+```
+
+In your custom checkers, you can call the ```ip``` checker function ```IsIp``` to validate the user input. Here is an example:
+
+```golang
+result := IsIp("2001:db8::68")
+
+if result != ResultValid {
+  // Send the mistakes back to the user
+}
+```
