CAIDA::ASFinder::load_file_text(STR filename)
- This function loads in a parsed route table output by parse_bgp_dump
and stores the data internally. This function must be called before

- dotted_ip: The dotted IP address to find an AS for.
- Returns a list of AS number, network, and netmask if successful,
or a list of false values if no AS/network could be found.
- Sample call:
($as, $net, $mask) =
$as_finder->get_as("192.172.226.30");
CAIDA::ASFinder::get_as_raw(SCALAR binary_ip)
- Like get_as, but uses the raw (non-string) IP address.
- binary_ip: The IP address to find an AS for.
- Returns a list of AS number, network, and netmask if successful,
or a list of false values if no AS/network could be found.
- (Contrived) sample call:
use Socket;
$ip = inet_aton("192.172.226.30");
($as, $net, $mask) = $as_finder->get_as($ip);
