print "CIDR: " , join(",", $iana->cidr()) , "\n";DESCRIPTION
Various Net::Whois and IP:: modules have been created. This is just something I had to write because none of them s uited my purpose. It is conceptually based on Net::Whois::IP by Ben Schmitz <bschmitz@orbitz.com>, but differs from it by a few points:
- It is object-oriented.
- It has a few immediate methods for representing some whois fields.
- It allows the user to specify explicitly which whois servers to query, and those servers might even not be of the four main registries mentioned above.
- It has more robust error handling.
Net::Whois::IANA was designed to provide a mechanism to lookup whois information and store most descriptive part of it (descr, netname and country fields) in the object. This mechanism is supposed to be attached to a log parser (for example an Apache web server log) to provide various accounting and statistics information.
The query is performed in a roundrobin system over all four registries until a valid entry is found. The valid entry stops the main query loop and the object with information is returned. Unfortunately, the output formats of each one of the registries is not completely the same and sometimes even unsimilar but some common ground was always found and the assignment of the information into the query object is based upon this common ground, whatever misleading it might be.
The query to the RIPE and APNIC registries are always performed with a '-r' flag to avoid blocking of the querying IP. Thus, the contact info for the given entry is not obtainable with this module. The query to the ARIN registry is performed with a '+' flag to force the colon-separated output of the information.
NAME
Net::Whois::IANA - A universal WHOIS data extractor.
ABSTRACT
This is a simple module to extract the descriptive whois information about various IPs as they are stored in the four regional whois registries of IANA - RIPE (Europe, Middle East) APNIC (Asia/Pacific), ARIN (North America), AFRINIC (Africa) and LACNIC (Latin American & Caribbean).
It is designed to serve statistical harvesters of various access logs and likewise, therefore it only collects partial and [rarely] unprecise information.
METHODS
For the convenience of the user, basic list of IANA servers (@IANA) and their mapping to host names and ports (%IANA) are being exported.
Also the following methods are being exported:
$iana->whois_query
Perform the query on the ip specified by $ip. You can limit the lookup to a single server (of the IANA list) by specifying '-whois=>$whois' pair or you can provide a set of your own servers by specifying the '-mywhois=>\%mywhois' pair. The latter one overrides all of the IANA list for lookup. You can also set -debug option in order to trigger some verbosity in the output.
$iana->whois_query(-ip=>$ip,-whois=>$whois|-mywhois=>\%mywhois)$iana->descr()
Returns some of the "descr:" field contents of the queried IP.
$iana->netname()
Returns the "netname:" field contents of the queried IP.
$iana->country()
Returns "country:" field contents of the queried IP. Useful to combine with the Geography::Countries module.
$iana->inetnum()
Returns the IP range of the queried IP. Often it is contained within the inetnum field, but it is calculated for LACNIC.
$iana->status()
Returns the "status:" field contents of the queried IP.
$iana->source()
Returns the "source:" field contents of the queried IP.
$iana->server()
Returns the server that returned most valuable ntents of the queried IP.
$iana->cidr()
Returns an array in CIDR notation (1.2.3.4/5) of the IP's registered range.
$iana->fullinfo()
Returns the complete output of the query.
$iana->is_mine($ip,@cidrrange)
Checks if the ip is within one of the CIDR ranges given by @cidrrange. Returns 0 if none, 1 if a range matches.
$iana->abuse()
Yields the best guess for the potential abuse report email address candidate. This is not a very reliable thing, but sometimes it proves useful.
BUGS
As stated many times before, this module is not completely homogeneous and precise because of the differences between outputs of the IANA servers and because of some inconsistencies within each one of them. Its primary target is to collect info for general, shallow statistical purposes. The is_mine() method might be optimized.
CAVEATS
The introduction of AFRINIC server may create some confusion among servers. It might be that some entries are existant either in both ARIN and AFRINIC or in both RIPE and AFRINIC, and some do not exist at all. Moreover, there is a border confusion between Middle East and Africa, thus, some Egypt sites appear under RIPE and some under AFRINIC. LACNIC server arbitrarily imposes query rate temporary block. ARIN "subconciously" redirects the client to appropriate server sometimes. This redirection is not reflected yet by the package.
