You're right on all points. However, given Google's entry into this now, what motivation does any ISP have left for running its own DNS servers?

- pyre 17y agoKeeping traffic on it's own network vs having all DNS queries making a round-trip between their network and Google's DNS (ala Level3)? It's not like ISPs have ever needed an excuse to try and 'cut costs' by skimping on services. The difference is a greater majority of their customers use DNS than USENET.
- thaumaturgy 17y agoDNS doesn't occupy a lot of bandwidth. DNS servers on the other hand can be irksome to deal with if you don't have to. Small ISPs are merely resellers; if their DSL customers f'rinstance use Google's DNS servers instead of the ISPs, the ISP actually has less network traffic coming into their racks. Plus, they no longer have to admin a DNS server. For larger ISPs, it may still be less trouble to just let their customers use Google's DNS instead.
