Blogging via DNS
txtrex stores blog posts in TXT records: query one name to list posts and another to retrieve a post, making publishing possible with DNS alone.

txtrex publishes posts as DNS TXT records. One query lists available posts; another retrieves a post’s text.
That makes the publishing path easy to inspect with DNS tools, but it inherits the size limits, cache behaviour, and update delay of DNS.
