Geo IP Filter Tip:

If you think you’re helpless when it comes to controlling where your web traffic comes from, think again! With Constellix’s IP Filter rules, you can now raise your mighty sword and yell: “By the power of Greyskull, I have the power!” Well, maybe it’s not quite as dramatic as all of that, and it’s by the power of Constellix. And you won’t turn into He-man or She-ra. And your cat won’t turn into Battlecat, but still …

With IP Filters at your disposal, you’ll at least feel the power of DNS. Using Constellix’s IP Filters, you can prevent traffic from certain regions from accessing your site or application. When you set up IP Filter rules, you’re actually creating a firewall on DNS level.

Here are a few examples of how you can utilize filtering in Constellix:

DDoS Mitigation

Suspicious activity coming from a specific region can be blocked. This works best when paired with DNS monitoring, such as our Real-time Traffic Anomaly Detection service. You can block by region, country, state, city, or even /24 IPv4 EDNS, /120 IPv6 subnets and Autonomous System Networks (ASNs).

DNS Business Decisions

It may not seem like DNS would help make decisions that would benefit ROI, but with IP filters you can do just that. Let’s say your business only services your country, state, or even city. IP filtering lets you effectively block queries from regions outside of your service area, even down to the city level. This streamlines your traffic and makes your domain more efficient.
