If it were true that TTL's are fixed at 1 day, then the service would be nearly unusable. TTL's must be adjustable or else fixed using a fairly short time span. When I do lookups of opensrs.org and tucows.com, however, I see TTL's of 10 minutes on everything. I'd say that's acceptable. As for refresh, retry, and expire, those are values that only affect zone updates to secondary DNS servers. If they're using BIND and NOTIFY's then they're not particularly important. Or they may even be running all name servers as masters. I can see how the visible 'names' of the name servers might be an impediment to what you're calling a "white label" service. But if you think about it, there are some major drawbacks to offering a DNS service where your name servers are registered in other domains. I'm sure you'd like to go into your domain registstration and register their servers as if they were your own, but imagine the total chaos that would ensue if Tucows were ever forced to move a server to a new IP address. Or if they added new servers, say in Europe or the far East, it's unlikely that many existing zone managers would ever add them. I really don't think this is doable unless you can be sure the addresses and the number of existing name servers will never change. Short of offering managed, dedicated servers, I fail to see how anyone could offer a true "white label" service for DNS.
