Sorry, I've been not specific enough here.
I meant e.g. several companies who have their own local subnets and local
If they don't use their ISP's servers then the local DNS server in every
company would contact the root DNS servers directly.
If they used their ISP's DNS servers then all customers of the same ISP
simply get the cached results for popular domains without having to contact
the root servers.
Of cause all of this discussion is based on assumptions, how much traffic
and load on the root servers would differ if people used them rather then
their ISP's servers.
