Questions & Answers

As answered by people managing Subnetter and DevSubnet.

What makes your product unique?

DevSubnet's answer:

Generates 1-click configuration code for Terraform, Ansible, and CloudFormation.

Why should a person choose your product over its competitors?

DevSubnet's answer:

Legacy subnet calculators are often ad-heavy, send IP parameters to remote backend servers, and assume a generic two-IP loss per subnet (network and broadcast). DevSubnet eliminates security risks by processing everything locally with zero latency, while reflecting modern cloud-native realities—such as multi-AZ cloud VPC offsets, visual recursive subnet splitting, and direct IaC syntax generation.

How would you describe the primary audience of your product?

DevSubnet's answer:

The primary audience includes DevOps engineers, cloud architects (AWS, Azure, GCP), network administrators, and CCNA/CCNP certification students who need fast, secure, and mathematically precise IP planning without leaking infrastructure details.

What's the story behind your product?

DevSubnet's answer:

Network engineers and DevOps professionals frequently plan private VPCs and Kubernetes clusters, yet most available subnet tools require transmitting sensitive CIDR blocks across the wire to unknown servers. DevSubnet was built to create a privacy-first, zero-log alternative that treats subnet calculation as an essential, high-speed developer utility with modern cloud support.

Which are the primary technologies used for building your product?

DevSubnet's answer:

DevSubnet is built as a static, client-side web application utilizing modern JavaScript/TypeScript, HTML5, and Tailwind CSS. All mathematical derivations, bitwise manipulations, and CIDR calculations run locally within the user's browser engine with zero backend compute requirements.

Who are some of the biggest customers of your product?

DevSubnet's answer:

  • Independent Cloud Architects & Network Consultants
  • DevOps & SRE Teams managing multi-cloud VPCs
  • CCNA, CCNP, and AWS/Azure Certified Solutions Architect candidates
