# NAME
|
||
|
|
|
||
|
|
mmdblookup - a utility to look up an IP address in a MaxMind DB file
|
||
|
|
|
||
|
|
# SYNOPSIS
|
||
|
|
|
||
|
|
mmdblookup --file [FILE PATH] --ip [IP ADDRESS] [DATA PATH]
|
||
|
|
|
||
|
|
# DESCRIPTION
|
||
|
|
|
||
|
|
`mmdblookup` looks up an IP address in the specified MaxMind DB file. The
|
||
|
|
record for the IP address is displayed in a JSON-like structure with type
|
||
|
|
annotations.
|
||
|
|
|
||
|
|
If an IP's data entry resolves to a map or array, you can provide a lookup
|
||
|
|
path to only show part of that data.
|
||
|
|
|
||
|
|
For example, given a JSON structure like this:
|
||
|
|
|
||
|
|
```js
|
||
|
|
{
|
||
|
|
"names": {
|
||
|
|
"en": "Germany",
|
||
|
|
"de": "Deutschland"
|
||
|
|
},
|
||
|
|
"cities": [ "Berlin", "Frankfurt" ]
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
You could look up just the English name by calling mmdblookup with a lookup
|
||
|
|
path of:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mmdblookup --file ... --ip ... names en
|
||
|
|
```
|
||
|
|
|
||
|
|
Or you could look up the second city in the list with:
|
||
|
|
|
||
|
|
```bash
|
||
|
|
mmdblookup --file ... --ip ... cities 1
|
||
|
|
```
|
||
|
|
|
||
|
|
Array numbering begins with zero (0).
|
||
|
|
|
||
|
|
If you do not provide a path to lookup, all of the information for a given IP
|
||
|
|
will be shown.
|
||
|
|
|
||
|
