```
IP table.lookup_ip(ID id, STRING key, IP default)
```

**Available in:** all subroutines

Looks up the key `key` in the table `id`. When the key is present, its
associated value will be returned. When the key is absent, the `default`
value is returned. The default value is required.

## Example

```vcl
table overrides IP {
  "/a": "203.0.113.0",
  "/b": "203.0.113.1",
  "/c": "203.0.113.2",
}

set client.geo.ip_override = table.lookup_ip(overrides, req.url.path, client.ip);
```
