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

Country codes are maintained by the RIPE Network Coordination Centre,
|
|||
|
|
in coordination with the ISO 3166 Maintenance Agency at DIN Berlin. The
|
|||
|
|
authoritative source of counry code mappings is:
|
|||
|
|
|
|||
|
|
<url:ftp://info.ripe.net/iso3166-countrycodes>

This script also knows about non-geographic top-level domains.
|
|||
|
|
|
|||
|
|
Usage: world [-d] [-p file] [-o] [-h] addr [addr ...]
|
|||
|
|
|
|||
|
|
--dump
|
|||
|
|
-d
|
|||
|
|
Print mapping of all top-level domains.
|
|||
|
|
|
|||
|
|
--parse file
|
|||
|
|
-p file
|
|||
|
|
Parse an iso3166-countrycodes file extracting the two letter country
|
|||
|
|
code followed by the country name. Note that the three letter country
|
|||
|
|
codes and numbers, which are also provided in the standard format
|
|||
|
|
file, are ignored.
|
|||
|
|
|
|||
|
|
--outputdict
|
|||
|
|
-o
|
|||
|
|
When used in conjunction with the `-p' option, output is in the form
|
|||
|
|
of a Python dictionary, and country names are normalized
|
|||
|
|
w.r.t. capitalization. This makes it appropriate for cutting and
|
|||
|
|
pasting back into this file.
|
|||
|
|
|
|||
|
|
--reverse
|
|||
|
|
-r
|
|||
|
|
Force reverse lookup. In this mode the address can be any Python
|
|||
|
|
regular expression; this is matched against all country names and a
|
|||
|
|
list of matching mappings is printed. In normal mode (e.g. without
|
|||
|
|
this flag), reverse lookup is performed on addresses if no matching
|
|||
|
|
country code is found.
|
|||
|
|
|
|||
|
|
-h
|
|||
|
|
--help
|
|||
|
|
Print this message.
