How to find Google IPs ranges

To find Google DNS records with ip ranges follow next steps

1. Get Google SPF record for the current list of IP addresses

nslookup -q=TXT _spf.google.com 8.8.8.8 At this step you should get next answer from the server

Server:         8.8.8.8
Address:        8.8.8.8#53

Non-authoritative answer:
_spf.google.com text = "v=spf1 include:_netblocks.google.com include:_netblocks2.google.com include:_netblocks3.google.com ~all"

2. Extract a list of Google's SPF record, such as

_netblocks.google.com, _netblocks2.google.com, _netblocks3.google.com

3. Look up the DNS records associated with those domains

nslookup -q=TXT _netblocks.google.com 8.8.8.8 At this step you should get next answer from the server

Server:         8.8.8.8
Address:        8.8.8.8#53

Non-authoritative answer:
_netblocks.google.com   text = "v=spf1 ip4:64.233.160.0/19 ip4:66.102.0.0/20 ip4:66.249.80.0/20 ip4:72.14.192.0/18 ip4:74.125.0.0/16 ip4:108.177.8.0/21 ip4:173.194.0.0/16 ip4:209.85.128.0/17 ip4:216.58.192.0/19 ip4:216.239.32.0/19 ~all"

4. Extract a list of Google's IPs

ip4:64.233.160.0/19 ip4:66.102.0.0/20 ip4:66.249.80.0/20 ip4:72.14.192.0/18 ip4:74.125.0.0/16 ip4:108.177.8.0/21 ip4:173.194.0.0/16 ip4:209.85.128.0/17 ip4:216.58.192.0/19 ip4:216.239.32.0/19
