Thanks for your message. When using a private collaborator server, your private collaborator server will run a DNS service for a specific domain (the one that it controls). You will need to make sure that all DNS requests for your collaborator domain are delegated to your private collaborator server. The exact steps to configure this will depend on your setup, but most domain registrars provide a web interface allowing you to configure the authoritative DNS servers for your domain. https://portswigger.net/burp/documentation/collaborator/deploying#dns-configuration I hope this helps, please let us know if you have any questions.

It's ok, but how it will work in a corporate network, where NS servers already exist? My network admin said, that we will must reconfigure our all network for work with only Burp Collaborator DNS and it is unacceptable. What are we missing? How we must config our network for work with it? Thanks
