Currently, comments for DNS seed filtering are not updated, as discussed here and here. Opening a pull request to update the comments can be noisy. Therefore, I have modified this script to generate all possible combinations of service flags along with their corresponding hexadecimal values and include a function to check if a DNS provider supports a given combination of node services.
My proposal is to add a comment referencing this script to ensure all filters are obtained
