NAME

6       mmdblookup - a utility to look up an IP address in a MaxMind DB file
7

SYNOPSIS

9       mmdblookup --file [FILE PATH] --ip [IP ADDRESS] [DATA PATH]
10

DESCRIPTION

12       mmdblookup  looks  up  an  IP address in the specified MaxMind DB file.
13       The record for the IP address is displayed  in  a  JSON-like  structure
14       with type annotations.
15
16       If  an  IP's  data  entry resolves to a map or array, you can provide a
17       lookup path to only show part of that data.
18
19       For example, given a JSON structure like this:
20
21
22           {
23               "names": {
24                   "en": "Germany",
25                   "de": "Deutschland"
26               },
27               "cities": [ "Berlin", "Frankfurt" ]
28           }
29
30       You could look up just the English name by calling  mmdblookup  with  a
31       lookup path of:
32
33
34           mmdblookup --file ... --ip ... names en
35
36       Or you could look up the second city in the list with:
37
38
39           mmdblookup --file ... --ip ... cities 1
40
41       Array numbering begins with zero (0).
42
43       If  you  do  not provide a path to lookup, all of the information for a
44       given IP will be shown.
