Nice—this is the raw HTML for ICANN’s “List of Accredited Registrars” dropdown. Here’s a quick, copy-paste script you can run in your browser console on that page to extract everything and download a clean CSV (Registrar, IANA):
That’ll give you a tidy CSV of everything in the dropdown (including all those DropCatch.com #### LLC items). Want me to also generate subsets (e.g., only DropCatch.com, only Dynadot*, etc.) or format it as JSON?
