I can confirm that you can apparently not resolve "node.moneroworld.com" and "node.xmr.be" via tor. I didn't test across multiple exits because I assume it is not related to the exit.

I tested it against a tor DNSPort, I don't think that has anything todo with torsocks. (That is why I changed the component for this ticket on trac)

It is probably worth mentioning that node.moneroworld.com resolves to 32 A records, node.xmr.be resolve to 55 A records, which might be the problem here?

Has tor a limit on how much it can take?
