OneTaskFree Reference Datasets
TLS Cipher Suites, MAC Vendor Lookup, MIME Types and Paper Sizes
Reference tables that other tools on this site lean on, published on their own so you can search them, cite them and download them. Every table names the source it was built from and the date it was retrieved, and comes as a CSV file for spreadsheets and a JSON file for code. Nothing on these pages is estimated or scraped from another aggregator.

Where the numbers come from
Each table is built from the primary source for its subject: the IEEE registration authority for MAC address prefixes, the IANA registries for TLS cipher suites and media types, the ISO standard for paper sizes, the IEC for plug and socket types, and the vendors and platforms themselves for prices and upload limits. The source link and the date it was read sit directly under each table's title, so you can check a row against the original and see how old it is.
Dates and updates
Some of these tables almost never change, like paper sizes or plug types. Others move every few months, like model prices and video upload limits. The retrieval date tells you which version you are looking at. When a table is refreshed the date moves and the downloads are replaced at the same address, so a link to the CSV always returns the current version.
Downloads and reuse
The CSV opens in any spreadsheet and the JSON loads straight into a script. Registries and standards keep their own terms, which each page states next to the source; the compilation, cleaning and formatting on this site may be reused freely with a link back. Each page also carries Dataset structured data, which lets search engines list the table in dataset search results.
FAQ
Can I use these tables in my own work?
Yes. Download the CSV or JSON and use it in a spreadsheet, a report, an app or a test fixture. Cite the original source named on each page, and link back to the page if you can so readers can find the current version and its retrieval date.
How current is each table?
Each page shows the date the source was retrieved, directly under the title and again in the citation line. Standards-based tables change rarely. Price and platform-limit tables change often, so check the date before relying on a figure, and follow the source link for anything that matters.
Why is only part of a large table shown?
Very large tables such as the MAC vendor list hold tens of thousands of rows, so the page shows the first two hundred matches for your search rather than drawing every row at once. The downloads always contain the complete table, whatever you have searched for.
