## Public methods

### isNumericAddress

Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static boolean isNumericAddress (String address)
```

Checks to see if the `address` is a numeric address (such as `"192.0.2.1"` or
`"2001:db8::1:2"`).

A numeric address is either an IPv4 address containing exactly 4 decimal numbers or an
IPv6 numeric address. IPv4 addresses that consist of either hexadecimal or octal digits or
do not have exactly 4 numbers are not treated as numeric.

This method will never do a DNS lookup.

<br />

| Parameters ||
|---|---|
| `address` | `String`: the address to parse. This value cannot be `null`. <br /> |

| Returns ||
|---|---|
| `boolean` | true if the supplied address is numeric, false otherwise. <br /> |

### parseNumericAddress

Added in [API level 29](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public static InetAddress parseNumericAddress (String address)
```

Returns an InetAddress corresponding to the given numeric address (such
as `"192.168.0.1"` or `"2001:4860:800d::68"`).

See `https://developer.android.com/reference/android/net/InetAddresses#isNumericAddress(java.lang.String)` (String)} for a definition as to what constitutes a
numeric address.

This method will never do a DNS lookup.

<br />

| Parameters ||
|---|---|
| `address` | `String`: the address to parse, must be numeric. This value cannot be `null`. <br /> |

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/net/InetAddress` | an `https://developer.android.com/reference/java/net/InetAddress` instance corresponding to the address. This value cannot be `null`. <br /> |

| Throws ||
|---|---|
| `https://developer.android.com/reference/java/lang/IllegalArgumentException` | if `address` is not a numeric address. |
