There are already tools existing for dyndns that are free. If you're using cloud flare as your dns provider, there's cloudflareddns that checks your public ip and updates dns records. You just need 1 record to be updated, the other records can just be CNAME to that primary one.
OVH has DynHost to deal with that as well.
You could also write a script to do that with your own DNS provider if one doesn't exist yet. Most have good APIs you can use to that extent. At worse just use cloudflare since it just works and is well supported.
