Generate a simple static report for DNS blocklists or see previous reports of requested blocklists.
View all blocklist reports here.
Feel free to request new features!
To check if a specific domain is present in a blocklist try:
- Open a new issue: Check a blocklist
- Enter the URL to the raw file of the blocklist
Supported formats: Domains, Adblock Plus, Hosts - Make yourself a coffee or tea while the report generates
(may take exponential longer for larger blocklists) - The GitHub Actions bot will reply with the report
See what is included in the report below.
The number of entries in the blocklist calculated after removing comments and the [Adblock Plus] header.
The number of entries after compression via AdGuard's Hostlist Compiler.
The following transformations are applied:
- RemoveComments
- Compress
- RemoveModifiers
These transformations remove redundant rules and strip modifiers to format the blocklist to domains.
The percentage next to the count is the entries compressed from the total raw entries (a higher percentage means higher compression).
Note that the compressed blocklist is used for all further processing.
An estimate of the percentage of domains found unresolving by AdGuard's Dead Domains Linter.
For blocklists with more than 1000 compressed entries, only 50% of the domains are selected for the dead check and used to calculate the percentage. This selection is done at random and capped at 10,000 domains.
The selected domains provide a reasonable representation of the percentage of dead domains in the blocklist with a deviation of about ±2 while reducing processing time.
The number of entries deemed invalid and removed by the Hostlist Compiler. Expanding the dropdown reveals the entries removed (limited to 1000 entries).
The following transformations are applied:
- RemoveComments
- Deduplicate
- Compress
- Validate
- TrimLines
- InsertFinalNewLine
These transformations remove non-domain entries like IP addresses and Unicode. Unicode in blocklists should be converted to Punycode for compatibility.
The percentage next to the count is the entries removed from the total compressed entries.
An estimate of the percentage of potential domains that can be used in a DNS blocklist.
domains usable = compressed entries - dead domains - invalid entries
The number of domains found in the Tranco Top Sites Ranking. Expanding the dropdown reveals the domains found (limited to 1000 entries).
The number of domains that were not found in the specified blocklist in column two. See the list of blocklists configured for comparison here: blocklists_to_compare.txt
The percentage shows what percent of domains are unique to the blocklist being checked.
The number of occurrences for the top 15 top-level domains (TLDs) in the compressed entries.
Time taken in seconds to download the blocklist and generate the report.
Note that the time taken to download dependencies/restore cache is excluded from this calculation.
