I can't set the IP range on Firewall


#1

I want to put these IP range into whitelist on cloudflare.

But, I don’t know how to set the IP range on Firewall menu.

Please help

192.0.80.0-192.0.95.255 (in CIDR notation 192.0.80.0/20)
192.0.96.0-192.0.111.255 (in CIDR notation 192.0.96.0/20)
192.0.112.0-192.0.127.255 (in CIDR notation 192.0.112.0/20)

You’ll have to go with a /16, or a bunch of /24 entries:

192.0.0.0/16

Or:
192.0.80.0/24
192.0.81.0/24
and so on.

Thanks.

Could you translate those 3 IP to a /16?

192.0.80.0/20
192.0.96.0/20
192.0.112.0/20

No. A /16 covers the entire last two octets: 192.0.XXX.XXX (192.0.0.0 – 192.0.255.255)
A /24 only covers the last octet: 192.0.80.XXX (192.0.80.0 – 192.0.80.255)
