6 This script will take a list of Internet addresses and print out where in the
|
|
|
7 world those addresses originate from, based on the top-level domain country
|
|
|
8 code found in the address. Addresses can be in any of the following forms:
|
|
|
9
|
|
|
10 xx -- just the country code or top-level domain identifier
|
|
|
11 host.domain.xx -- any Internet host or network name
|
|
|
12 somebody@where.xx -- an Internet email address
|
|
|
13
|
|
|
14 If no match is found, the address is interpreted as a regular expression [*]
|
|
|
15 and a reverse lookup is attempted. This script will search the country names
|
|
|
16 and print a list of matching entries. You can force reverse mappings with the
|
|
|
17 `-r' flag (see below).
|
|
|
18
|
|
|
19 For example:
|
|
|
20
|
|
|
21 %% world tz us
|
|
|
22 tz originated from Tanzania, United Republic of
|
|
|
23 us originated from United States
|
|
|
24
|
|
|
25 %% world united
|
|
|
26 united matches 6 countries:
|
|
|
27 ae: United Arab Emirates
|
|
|
28 uk: United Kingdom (common practice)
|
|
|
29 um: United States Minor Outlying Islands
|
|
|
30 us: United States
|
|
|
31 tz: Tanzania, United Republic of
|
|
|
32 gb: United Kingdom
|
|
|
33
|
|
|
34
|
|
|
35 [*] Note that regular expressions must conform to Python 1.5's re.py module
|
|
|
36 syntax. The comparison is done with the search() method.

38 Country codes are maintained by the RIPE Network Coordination Centre,
|
|
|
39 in coordination with the ISO 3166 Maintenance Agency at DIN Berlin. The
|
|
|
40 authoritative source of counry code mappings is:

50 Usage: world [-d] [-p file] [-o] [-h] addr [addr ...]
|
|
|
51
|
|
|
52 --dump
|
|
|
53 -d
|
|
|
54 Print mapping of all top-level domains.
|
|
|
55
|
|
|
56 --parse file
|
|
|
57 -p file
|
|
|
58 Parse an iso3166-countrycodes file extracting the two letter country
|
|
|
59 code followed by the country name. Note that the three letter country
|
|
|
60 codes and numbers, which are also provided in the standard format
|
|
|
61 file, are ignored.
|
|
|
62
|
|
|
63 --outputdict
|
|
|
64 -o
|
|
|
65 When used in conjunction with the `-p' option, output is in the form
|
|
|
66 of a Python dictionary, and country names are normalized
|
|
|
67 w.r.t. capitalization. This makes it appropriate for cutting and
|
|
|
68 pasting back into this file.
|
|
|
69
|
|
|
70 --reverse
|
|
|
71 -r
|
|
|
72 Force reverse lookup. In this mode the address can be any Python
|
|
|
73 regular expression; this is matched against all country names and a
|
|
|
74 list of matching mappings is printed. In normal mode (e.g. without
|
|
|
75 this flag), reverse lookup is performed on addresses if no matching
|
|
|
76 country code is found.
