How to open access to maps.google.com:80 on the firewall (over IP)?

Question

Google

You need to open access to maps.google.com:80 for the server, but for technical reasons you need to do it by ip (i.e. open access to FW). What ip range does maps.google.com use in its work? nslookup gives out a new range of addresses almost every hour, and sometimes it gives out addresses of servers that do not belong to Google, but to Rostelecom (CDN).

Answer 1

No way. You can try the pools above, but you yourself mentioned the CDN .. If you only write a script that will do nslookup by cron, then determine the pool of addresses by whois and register it all in iptables (or whatever fw you have there)

Answer 2

Maps.google.com resolves from these pools.
