 Posted: Fri 04 Jun '21 5:43 Post subject: Proper Syntax For White Listing IPs Using "Require IP&q |
 |

I am trying to limit connection to my proxy server through ip white listing and have difficulty putting the proper range of ip's.
I know the "Require ip" syntax from Apache documentation here :
http://httpd.apache.org/docs/current/mod/mod_authz_core.html#require
But the one example that they have is a bit vague to me.
So my requirements are to whitelist these IP's
173.245.48.0/20
103.21.244.0/22
is the following syntax valid:
Require ip 173.245.48 103.21.244
Can someone correct me if I am wrong.
Appreciate your help |

Your networks are not on 8 bit boundaries, so I'd suggest you need to use CIDR notation:
| Code: | Require ip 173.245.48.0/20
Require ip 103.21.244.0/22 |
I'd use two separate entries to ease management. |
