An IP based policy can be created by schools that have multiple public IPs and they want to create a unique policy for an individual IP.
You can create an IP based policy by logging into your Securly Admin console and navigating to Policy Editor > Custom Policy. You would then need to select the radio button for ‘This is an IP policy?’ and give it a name. Next, enter the IP address you want to create the policy for. Note that the IP address must be registered with Securly to create the policy.
If you are using Securly's old UI, please check out the KB here.
