Currently I'm allowing users to have an hosted application. Currently they have to point A-records to our servers (sometimes this is to hard or get's messy). I've seen other players using 2 dns servers, so that the user only needs to change these. I'm willing to implement this, but a lot of questions come up.
- What should I use for this? Can I use bind?
- The records need to be generated from a mysql database
- What type of servers do I need? Is a DNS server taking a lot of load? Currently having around 80K daily visitors.
