Your DNS server is wasting memory.
Based on Cloudflare's public optimization method, get a 3-page audit report showing exactly where your cache leaks memory — and how to fix it.

Why DNS cache memory matters right now
When Cloudflare revealed they saved 100 terabytes of memory by optimizing their 1.1.1.1 DNS cache, the discussion on Hacker News exploded — 621 points and 188 comments in hours. The top comments weren't about Cloudflare's scale; they were from engineers saying "our BIND servers are eating 128GB each and we don't know why." That's the signal: memory is the hidden tax of running your own DNS.
Existing tools fail you. BIND's built-in statistics dump raw counters — you still have to interpret them. Datadog monitors metrics but doesn't tell you which domain is wasting 2GB or that your TTL for API records is 10x too long. You're left with guesswork and expensive over-provisioning.
Now is the perfect time. Cloudflare's methodology is public, and the pressure on infrastructure costs is higher than ever. Every GB of memory you reclaim is pure savings on your cloud bill. This is a cost problem with a clear, actionable answer — and it's never been more accessible.
How It Works
Upload your DNS logs
Export your BIND, Unbound, PowerDNS, or Knot query logs. No agent installation — just a simple file upload. We accept standard formats and parse them securely.
We analyze cache efficiency
Our engine calculates hit rates per domain, identifies record types that occupy memory but are rarely accessed, and pinpoints TTL misconfigurations — all using Cloudflare's published optimization logic.
Get your actionable report
Receive a concise 3-page HTML report within minutes. It lists your top 10 memory waste points, shows hit-rate trends, and gives you specific configuration changes — with code snippets — to reclaim memory.
What You Get
Save real money
Our audits typically uncover 30%+ wasted cache memory. For a server running 128GB RAM, that's over 38GB reclaimed — translating to thousands of dollars in annual cloud savings. The report shows you the exact dollar impact.
Actionable fixes
No vague advice. Every recommendation includes a concrete configuration snippet — whether it's adjusting TTL values, tweaking LRU parameters, or implementing a sharding strategy. You can apply the changes immediately and measure the impact.
Fast & lightweight
Upload your logs and get the full report in about 5 minutes. No complex setup, no agents, no perpetual monitoring. It's a one-time audit that gives you a clear before-and-after picture of your DNS memory efficiency.
