Google Search is actually a useful way to find sites on a TLD:
https://www.google.com/search?q=site%3Agoogle https://www.google.com/search?q=site%3Agle https://www.google.com/search?q=site%3Agoog
https://www.google.com/search?q=site%3Agoogle https://www.google.com/search?q=site%3Agle https://www.google.com/search?q=site%3Agoog
You can combine the exclusion `-` syntax with this as well. If you want to find different sites on the TLD `.test` but only URLs on `home.test` are being shown, you can use this search:
site:test -site:home.test
