hi everyone, I am kind of new to this forum. I need help in sorting this data out accordingly, I am actually doing a traceroute application and wants my AS path displayed in front of my address like this;
192.168.1.1 AS28513 AS65534 AS5089 AS5089 .... till the last AS number and if possible sort for uniq AS number so that there wont repetion as it occurs below.
From data like below:
Thanks for you anticipated help.

how can i sort the next list just by look at the numbers (ignore letters)
example:
abc123
dff4f
aaa2aa
bbbb55555bb
output:

net::ipv4addr
IPv4Addr(3pm) User Contributed Perl Documentation IPv4Addr(3pm)NAME
Net::IPv4Addr - Perl extension for manipulating IPv4 addresses.
SYNOPSIS
use Net::IPv4Addr qw( :all );
my ($ip,$cidr) = ipv4_parse( "127.0.0.1/24" );
my ($ip,$cidr) = ipv4_parse( "192.168.100.10 / 255.255.255.0" );
my ($net,$msk) = ipv4_network( "192.168.100.30" );
my $broadcast = ipv4_broadcast( "192.168.100.30/26" );
if ( ipv4_in_network( "192.168.100.0", $her_ip ) ) {
print "Welcome !";
}
etc.
DESCRIPTION
Net::IPv4Addr provides functions for parsing IPv4 addresses both in traditional address/netmask format and in the new CIDR format. There
are also methods for calculating the network and broadcast address and also to check if a given address is in a specific network.
ADDRESSES
All of Net::IPv4Addr functions accept addresses in many formats. The parsing is very liberal.
All these addresses would be accepted:
127.0.0.1
192.168.001.010/24
192.168.10.10/255.255.255.0
192.168.30.10 / 21
10.0.0.0 / 255.0.0.0
255.255.0.0
Those wouldn't though:
272.135.234.0
192.168/16
Most functions accepts the address and netmask or masklength in the same scalar value or as separate values. That is either
my($ip,$masklength) = ipv4_parse($cidr_str);
my($ip,$masklength) = ipv4_parse($ip_str,$msk_str);
USING
No functions are exported by default. Either use the ":all" tag to import them all or explicitly import those you need.
FUNCTIONS
ipv4_parse
my ($ip,$msklen) = ipv4_parse($cidr_str);
my $cidr = ipv4_parse($ip_str,$msk_str);
my ($ip) = ipv4_parse($ip_str,$msk_str);
Parse an IPv4 address and return in scalar context the address in CIDR format, in an array context the address and the mask length.
If the parameters doesn't contains a netmask or a mask length, in scalar context only the IPv4 address is returned and in an array
context the mask length is undefined.
If the function cannot parse its input, it croaks. Trap it using "eval" if you don't like that.
ipv4_broadcast
my ($broadcast) = ipv4_broadcast($ip_str);
my $broadcast = ipv4_broadcast($ip_str,$msk_str);
This function returns the broadcast address. If the input doesn't contain a netmask or mask length, the default netmask is assumed.
This function croaks if the input is invalid.
ipv4_network
my $cidr = ipv4_network($ip_str);
my $cidr = ipv4_network($cidr_str);
my ($net,$msk) = ipv4_network( $net_str, $msk_str);
In scalar context, this function returns the network in CIDR format in which the address is. In array context, it returns the network
address and its mask length as a two elements array. If the input is a host without a netmask or mask length, the default netmask is
assumed.
Again, the function croaks if the input is invalid.
ipv4_in_network
print "Yes" if ipv4_in_network( $cidr_str1, $cidr_str2);
print "Yes" if ipv4_in_network( $ip_str1, $mask_str1, $cidr_str2 );
print "Yes" if ipv4_in_network( $ip1, $mask1, $ip2, $msk2 );
This function checks if the second network is contained in the first one and it implements the following semantics :
If net1 or net2 is a magic address (0.0.0.0 or 255.255.255.255)
then this function returns true.
If net1 is a host, net2 will be in the same net only if
it is the same host.
If net2 is a host, it will be contained in net1 only if
it is part of net1.
net2 is only part of net1 if it is entirely contained in
net1.
Trap bad input with "eval" or else.
ipv4_chkip
if ($ip = ipv4_chkip($str) ) {
# Do something
}
Return the IPv4 address in the string or undef if the input doesn't contain a valid IPv4 address.
ipv4_cidr2msk
my $netmask = ipv4_cidr2msk( $cidr );
Returns the netmask corresponding to the mask length given in the input. As usual, croaks if it doesn't like your input (in this case
a number between 0 and 32).
ipv4_msk2cidr
my $masklen = ipv4_msk2cidr( $msk );
Returns the mask length of the netmask in the input. As usual, croaks if it doesn't like your input.
