Question

Google is blocked in some countries. However, there are many ways to access Google, like VPN, agent, and by changing the hosts file.

Answer 1

Google maintains a server infrastructure that grows dynamically with the ever increasing internet demands. This link by google describes the method to remain up to date with their IP address ranges.

When you need the literal IP addresses for Google Apps mail servers, start by using one of the common DNS lookup commands (nslookup, dig, host) to retrieve the SPF records for the domain _spf.google.com, like so:

nslookup -q=TXT _spf.google.com 8.8.8.8

This returns a list of the domains included in Google's SPF record, such as: _netblocks.google.com, _netblocks2.google.com, _netblocks3.google.com

Now look up the DNS records associated with those domains, one at a time, like so:

nslookup -q=TXT _netblocks.google.com 8.8.8.8
nslookup -q=TXT _netblocks2.google.com 8.8.8.8
nslookup -q=TXT _netblocks3.google.com 8.8.8.8

The results of these commands contain the current range of addresses.

Answer 2

The following IP address ranges belong to Google:

64.233.160.0 - 64.233.191.255
66.102.0.0 - 66.102.15.255
66.249.64.0 - 66.249.95.255
72.14.192.0 - 72.14.255.255
74.125.0.0 - 74.125.255.255
209.85.128.0 - 209.85.255.255
216.239.32.0 - 216.239.63.255

Like many popular Web sites, Google utilizes multiple Internet servers to handle incoming requests to its Web site. Instead of entering http://www.google.com/ into the browser, a person can enter http:// followed by one of the above addresses, for example:

http://74.125.224.72/

Answer 3

Here is a bash script that returns the IP (v4 and v6) ranges using @WorkWise's answer:

domainsToDig=$(dig @8.8.8.8 _spf.google.com TXT +short | \
    sed \
        -e 's/"v=spf1//' \
        -e 's/ ~all"//' \
        -e 's/ include:/\n/g' | \
    tail -n+2)
for domain in $domainsToDig ; do
    dig @8.8.8.8 $domain TXT +short | \
        sed \
            -e 's/"v=spf1//' \
            -e 's/ ~all"//' \
            -e 's/ ip.:/\n/g' | \
        tail -n+2
done

Answer 4

If all you are trying to do is find the IP address that corresponds to a domain name, like google.com, this is very easy on every machine connected to the Internet.

Simply run the ping command from any command prompt. Typing something like

ping google.com

will give you (among other things) that information.
