A. No, our DNS Service that supports dynamic IP is 100% free for all domains regardless of the registrar of the domain. However, we do suggest you to have your domains with us by registering new domains or transferring existing domains to us. Domains with us do enjoy free services including URL Forwarding (with domain cloaking) that usually cost $6.99/year for domains out of our registry. Also, you get cheaper price for Email Forwarding Service.
We only live support domains with paid services (domain registration is considered paid service). Live supports include phone support and live chat support.
