Google compute engine IP ranges

googlegoogle-compute-engine

I'm trying to figure out what the IP ranges for google compute engine are.

I have a library that is locked for use on certain IP ranges. Crazy I know, it's a bit special.

I hunted around the google document ion but couldn't find a list.
Is there a way of looking this up or querying for it somehow?

As the other answer says, Google describes how to get the list here: https://cloud.google.com/compute/docs/faq#where_can_i_find_product_name_short_ip_ranges

I found a good script here for following spf records:

https://aplawrence.com/Kerio/recursive_spf.html

create the file lookup.perl as:

#!/usr/bin/perl
$domain=shift @ARGV;
@results=getit($domain);


sub getit {
  my $domain=shift;

  my @foo=`nslookup -q=TXT $domain`;
  my @results=();
  foreach (@foo) {
   next if not /$domain\ttext/;
   s/$domain\ttext = "v=spf1//;
   @results=split /\s+/;
   foreach (@results) {
    next if /-all/;
    print "$_\n";
    if (/include:/) {
     s/include://;
     getit($_);
    }
   } 
  } 
}

then run: ./lookup.perl _cloud-netblocks.googleusercontent.com | grep ip4
