About

We built IP-Atlas because ipinfo moved half its fields behind a $49/mo paywall.

In May 2025 ipinfo launched IPinfo Lite as its new free product — unlimited requests, but only country, continent, ASN and AS name. City, region, latitude, longitude, timezone, and privacy detection moved to the paid Core tier at $49/mo. Thousands of projects broke overnight. We rebuilt the same data — from the same public RIR feeds — and committed to keeping every field free on every plan.

ipinfo tier structure verified from ipinfo.io/pricing and ipinfo.io/lite, as of 2026-04-22.

Who operates this

IP-Atlas is operated by Trellis Digital Services LLC, a single-member US limited liability company. It ships alongside a handful of other Trellis products built on the same Go stack and the same operational discipline.

One operator. One Postgres. One Go binary. No venture capital. No sales team. Our cost to serve is low enough that we can price below the incumbents and still have margin. You can read the full cost model in our overage billing section.

What we do differently

Every field, every plan

City, region, coordinates, timezone, postal, ASN, organisation, datacenter, VPN. We don't ship partial data and charge you for the rest.

Fair overage, no surprise 429

Exceeding your quota doesn't cut your API off — it bills transparently at your plan's rate. Warnings at 80% and 95%. Set a spend cap if you want one.

No request-content logging

We count requests. We don't log the IPs you query. Our database has your email, your key hash, and two monthly counters. That's it.

MMDB if you want to self-host

Don't want outbound HTTP on every request? Download a monthly MMDB snapshot with the same fields.

Where the data comes from

The substrate is public — ARIN, RIPE NCC, APNIC, LACNIC, AFRINIC all publish daily delegated-extended files that assign every IPv4 prefix and every ASN to a country and an organisation. Cross-reference them and you have 256,000+ prefixes and 520,000+ ASNs covering every announced address on the internet, refreshed nightly.

Data-centre detection is a Trellis-maintained list of hosting provider IP ranges (AWS, Google Cloud, Azure, Cloudflare, DigitalOcean, OVH, Hetzner, Vultr, Linode/Akamai, et al.). VPN detection is the same list plus known VPN provider ASNs.

We don't do probabilistic ML city inference. Our city-level data comes from a combination of RIR city fields where present and authoritative geo feeds. We're honest about what's high-confidence and what isn't — see the accuracy notes.

Principles

  1. No paywalled fields. If we return it, you see it.
  2. Honest pricing. Overage is published, not buried. Cap it from the dashboard if you're anxious.
  3. Minimal data retention. We store what we need to bill you and nothing else.
  4. Single-operator transparency. Every page, endpoint, and invoice is mine. Email me with questions — I answer.
  5. Public source substrate. Our data foundation is RIR public records; we don't resell licensed proprietary data.

What's next

In order of ship-date: downloadable MMDB snapshots for Developer+; an EU endpoint for Business customers who need EU data residency; Snowflake export; and a probe network for accuracy validation against live traffic. See the status page for what's running right now.
