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>
|
||
|
||
The latest known change to this information was:
|
||
|
||
Thu Aug 7 17:59:51 MET DST 1997
|
||
|
||
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.
