whitelist ip range

Post by tubes_00 »

Hi,

I really need some help on how to whitelist IP ranges. I have tried adding the subnet into the whitelist on the mailwatch website but it doesn't seem to work when you use the IP and subnet mask.

Can someone help me adding the range of IP's. I need to whitelist the mailchimp IP ranges below.

205.201.128.0/20
198.2.128.0/18
148.105.0.0/16

I believe its (kind of) classful. (but not really)

Syntax: (Note trailing dot)

Class C: 192.168.10.
Class B: 192.168.
Class A 192.

To calculate the IP ranges you could use the Subnet Calculator https://mxtoolbox.com/subnetcalculator.aspx

CIDR _________ | CIDR IP Range
198.2.128.0/18 = 198.2.128.0 - 198.2.191.255

The best option is to sit down and take some time to read about CIDR notations ;) https://en.wikipedia.org/wiki/Classless ... in_Routing

I have the CIDR ranges. I just need to know where to enter them so we can whitelist the IP ranges.

205.201.128.0/20
198.2.128.0/18
148.105.0.0/16
