Traffic Filters

Our Traffic Filters feature lets you easily configure which IP addresses or IP ranges to exclude from your tracking. With this, you can enjoy cleaner, more accurate data without compromising on quality. This feature is available on the JENTIS DCP under Settings > Traffic Filters.

You can create filters excluding traffic by “IP matching” - an exact match to an IP - or by “IP is in range” - using the CIDR notation.

IP Address: What is it and how does it work?

Think of an IP address as the unique home address for your computer on the internet. For example, your home address tells the postal service where to deliver your mail, and your IP address tells the internet where to send data.

Without an IP address, your computer wouldn’t be able to connect to websites, send emails, or use online services because it wouldn’t have a way to identify itself and communicate with other devices.

When you connect to the internet, your Internet Service Provider (ISP) assigns your device an IP address. This IP address is how websites and online services know where to send the information you request.

When you want to visit a website, your computer sends a request to the website’s IP address. The internet uses these numbers to route your request to the correct location, just like a postal service uses addresses to deliver mail.

There are two types of IP addresses: IPv4 and IPv6.

• IPv4: Most common, looks like 192.168.1.1. It’s a series of four numbers separated by dots.

  • An octet is a group of 8 bits. In the context of an IPv4 address, it represents each of the four segments separated by dots.

  • Each octet can hold a value from 0 to 255 because 8 bits can represent 256 different values (2^8).

• IPv6: Newer and looks like 2001:0db8:85a3:0000:0000:8a2e:0370:7334. It’s longer and separated by colons.

  • A hextet is a group of 16 bits. In the context of an IPv6 address, it represents each of the eight segments separated by colons.

  • Each hextet can hold a value from 0 to 65535 because 16 bits can represent 65,536 different values (2^16).

  • IPv6 addresses are written in hexadecimal notation - each group can contain numbers and letters (from 0-9 and a-f).

Our Traffic Filters feature only supports IPv4 addresses at the moment.

What is a CIDR?

A subnet mask determines which part of the IP address is the network portion and which part is the host portion. If you think of an IP address as a phone number, the subnet mask helps separate the area code (network part) from the individual phone number (host part).

CIDR notation specifies an IP address and its associated network mask. It is written as an IP address followed by a slash (/) and a number that indicates the number of bits in the network portion of the address.

Example in IPv4:

→ Consider the address 192.168.1.0/24:

• The first 24 bits (192.168.1) are the network portion.

• The last 8 bits are for hosts (256 possible addresses from 192.168.1.0 to 192.168.1.255).

Example in IPv6:

→ Consider the address 2001:db8::/32:

• The first 32 bits (2001) are the network portion.

• The remaining 96 bits are for hosts (many possible addresses).

Our Traffic Filters feature only supports IPv4 addresses at the moment.

Currently, using the Traffic Filter function by container or tool is not possible. If activated, this configuration applies to all incoming traffic once the corresponding container version is published.

It’s also important to highlight that these filters are not applied to the data shown in the Preview Mode, so you can still see your own data flowing into the system.
