How do you set a CIDR/IP so anyone can access it from anywhere?
I’m trying to make my AWS RDS DB instance accessible from anywhere as my ISP doesn’t give me a static IP. Everytime my IP changes I have to go change the security record.
0.0.0.0/0does the trick on the EC2 firewall settingsA CIDR defines a range of IP addresses. In the CIDR notation above,
/0is saying "every possible IP".I like using http://cidr.xyz/ to visualize the range of addresses.
