Hi Harald,

Do you ever have seen a significant issue with this in real life?
Some companies I forward queries t, even give back their answers with a TTL of zero - so there is not even a theoretical difference in the TTL between forwarding and other means of resolution in these cases.

Mit freundlichen Grüßen
