Creating your own DNS(Domain Name System) Service is a complex task that requires a good understanding of the networking, DNS protocols, and server administration. It’s not a beginner’s base project, but if you have the necessary knowledge and are up for the challenge, here are the steps to get you how to start.

1、Plan and Design: Define the scope of your DNS service, will it be authoritative, recursive, or both?
2、Set up Hardware and Infrastructure: Get the necessary hardware or virtual machines to host your DNS Servers, ensure a reliable and high-speed internet connection.
3、Chose a Domain Names: You will need a domain name for your DNS service, and you will have to register it through a domain registrar.
4、Install DNS Server Software: Install and configure your chosen DNS server software on your servers. Configure it as an authoritative, recursive or a caching DNS server, depending on your requirements. Many open source DNS solution like Bind, PowerDNs, GunDNS etc.
5、Create DNS Zone Files: For an authoritative DNS server, you will need to create zone files that define the DNS records for the domains you want to manage. Learn the syntax of your DNS server software to create these zone files.
6、Set Up DESSEC(Optional): DNS security extensions(DNSSEC) provide and added layer of security to your DNS service. You can choose to implement it for additional security.
7、Network Configuration: Configure your network to route DNS traffic to your DNS Servers; ensure that your DNS server has static IP address
8、Testing and Debugging: Test your DNS server setup using tools like dig or nslookup; ensure that your DNS server resolves queries correctly.
9、Security Measures: Implement security measures to protect your DNS infrastructure. This includes access, control, firewalls and regular security updates.
10、Monitoring and Logging: implement monitoring and logging to keep track of DNS queries, errors and performance. Set up alerts for any unusual activity.
Lastly, remember that DNS is a critical part of the internet’s infrastructure, and mistakes can have far-reaching consequences. if you’re unsure about any aspect of this project, it’s a good idea to consult with experienced professionals or DNS experts.
