One method is to run your own name server and have a way to update the zone database with your dynamically updated entries. Might be simplest with an authoritative DNS server that can work directly from a database (like powerdns), though I have no idea how these work with replication and zone transfers, so you might need to run the same software on any secondary servers. Another option is to use generated zone files, and some normal server software like NSD or BIND. You could have secondary servers who receive updates to distribute the query load. As a dynamic DNS service has to use low TTLs there could be quite a lot of traffic for updates so look into software and providers that can do IXFR not just AXFR. This way you could use a standard secondary-DNS service (various free/commercial ones available). Alternatively outsource DNS hosting to a provider who has an API for making updates to zones (thinking something like amazon route 53 or dyn.com, *but* be aware that the ones I know of do not have good geographic distribution of servers outside of Europe and USA; nothing currently in or particularly close to India, though it is planned for dyn). Or you could do a blend, serve things locally at your own server/s and also push updates to an API-based provider if they need to be served globally..
