Blocking Rules allow you to control collection from certain IP addresses or ISPs that you do not wish to track and contribute to your data credit allowance. These can perhaps be internal IP addresses that you do not want to track, or the IP address of known bots perhaps.
To add a Blocking Rule, simply navigate to Settings > Blocking Rules from the left hand menu and click the Add Blocking Rule button. From here you need to select the relevant Scope: whether it is an IP address or an ISP. In the Rule field, you can add an individual IP address, multiple IP addresses (separated by commas), an IP range using a regex statement, or the name of the ISP that you wish to block. You can also add a description so that you know what is being filtered out.
You can also choose to whitelist IP addresses in the Type dropdown. To protect against collection from bots, if Decibel detects unusually high volumes of traffic from a single IP address, collection from that address will be automatically blocked. However, this can be prevented by selecting the Whitelist option.
Once happy, click Save Blocking Rule. You can edit or delete these at any time by clicking the relevant icons.
Please note: There is a limit of 250 Blocked IPs per account. Decibel may also automatically create Blocked IPs if unusual traffic patterns are detected while processing data.
How do I add multiple IPs?
If you have a large number of IP addresses that you don't want to track, don't worry, you don't have to add these one by one. If it is a range of IPs you can use a simple regex statement to determine the range that you want to block. For example, if you have an internal network where the IP range goes from 126.96.36.199 to 188.8.131.52, you can use the following statement to exclude these:
Alternatively, if you have a list of IP addresses, you can exclude these by using the following statement, replacing these IP addresses with your own:
Why are some IP addresses showing as "Automatic Block"?
To protect against collection from bots, if Decibel detects unusually high volumes of traffic from a single IP address, collection from that address will be automatically blocked.
Removing Blocked IPs
You can remove a Blocking Rule at any time by clicking the Delete icon next to the relevant Rule that you no longer wish to block or whitelist. This will result in Sessions from the respective IP address or ISP being collected, however does not work retrospectively so will not result in the collection of previous Sessions from that rule.
