# What kind of list formats are supported?

The eBlocker allows you to upload four different list formats:

## Easylist URL Pattern Format

Blocking lists in easylist format have the advantage to recognize **pattern**of trackers, ads and unwanted content in domains and URLs. This helps agains over-blocking, which takes place a lot with classic domain blocking (like DNS blocking for instance).

**Example**: *good-domain.com/badtracker.php* can be recognized by a pattern and will be blocked, whereas other URLs of the same domain like *good-domain.com/somecontent.php* will be accessible. In comparison to traditional domain blocking (see below) only the full domain *good-domain.com* can be blocked, resulting in over-blocking.

The easylist format is used by browser extensions such as AdBlock and others. It’s also the recommended format for eBlocker. There are many [blocking lists available in easylist format](https://eblocker.org/en/docs/where-can-i-find-block-lists-on-the-internet/).

Please find the [exact easylist format definition here](https://adblockplus.org/filter-cheatsheet). Please note that easylist is supported only on devices where eBlocker's [pattern blocker](https://eblocker.org/en/docs/what-are-domain-and-pattern-blockers/) is enabled.

```
Example: /adzone_/theadzone/*###adsontheright-advertise.$domain=~i-domain.net|~bad-domain.gr||domain.net^$third-part@@/ad_file/*$image,domain=domain.de|domains.debaddomain.com###IMU_468x60
```

## Domain List Format

Domain lists are lists which contain standard domain names.

```
Example: domain.comdomain.rubad.domain2.orgverybad.domain2.pwvery.bad123.domain3.net
```

## Squid-ACL List Format

Squid-acl lists are used by the Squid proxy server and similar to domain lists.

```
Example:domain.comdomain.rubad.domain2.orgverybad.domain2.pwvery.bad123.domain3.net
```

## etc.hosts List Format

The Unix/Linux operation system uses etc.host lists. These lists indicate the IP address before the domain. These are usually the IP address of the local host (127.0.0.1), or the IP address 0.0.0.0.

```
Example: 127.0.0.1 domain.com127.0.0.1 domain.ru127.0.0.1 bad.domain2.org127.0.0.1 verybad.domain2.pw127.0.0.1 very.bad123.domain3.net
```

## Note

For the **domain**, **squid-acl** and **ect.hosts** list, the # character indicates a comment. Everything in the same line after # is ignored.

```
Example:# This hosts file is brought to you by XXXXXXX# You are free to copy and distribute this file for non-commercial uses.# Last updated: Mon, 28 May 2019 at 06:53:40 GMT
