Is there a well-known public auction for .NL domains? I'm specifically looking for the largest one.

Domains that have been caught are sold through auctions. However, if you're interested in selling domains, there aren't many good auction sites available. Domains nl is one option, but it's a small site and not specifically an auction site. Sedo is another option that offers auctions, but it may not be the best choice unless you have top tier domains to sell.

It's important to note that finding the right auction site for selling domains can be a challenging task. There are many factors to consider, such as the size of the site, the audience it attracts, and the fees involved. Additionally, it's essential to have high-quality domains to offer if you want to see success with domain auctions.

As far as I know, the largest and most well-known public auction for .NL domains is the "Domeinveiling" by SIDN (Stichting Internet Domeinregistratie Nederland). This auction provides a platform for individuals and businesses to buy and sell .NL domains through a transparent and regulated process. It is highly reputable and widely recognized within the domain industry.

If you are interested in participating in domain auctions for .NL domains, I would recommend exploring the opportunities offered by SIDN's "Domeinveiling" as it is considered the primary auction platform for .NL domains.
