Using bgpview_query.ps1

 Get-SplunkASNPrefixSearch -ASN 32934

Or this module is broken into two separate cmdlets if you're into that sort of thing

$fb_prefixes = Invoke-BGPViewASNQuery -ASN 32934
Get-SPLForSubnets -PrefixList $fb_prefixes

Alternatively, you can save the query results and use them later to re-generate the SPL search string

Invoke-BGPViewASNQuery -ASN 32934 -CSVToFile ./as32934.csv
[...]
$prefixes = Import-CSV ./as32934.csv
Get-SPLForSubnets -PrefixList $prefixes.CIDR

This module is just for people that use Splunk and need to look up traffic for a certain ASN in splunk, it assumes the traffic logs exist in splunk with 'src_ip' and 'dest_ip' transformations applied and stored in the networking index. Adding -Verbose gives more data about CIDRs found for the ASN in a readable format

Notes

Use these at your own risk, don't be a dick either.
