Research Intern Summer

IPinfo is a leading provider of IP address data: geolocation, VPN and residential proxy detection, mobile carrier, IP to company, and more than 20 other context tags. Our API handles over 1 billion requests a day, and companies such as Cloudflare, T-Mobile, and SpaceX build our data into their products. We're a fast-growing, bootstrapped company with a fully remote team of more than 80 people.

We sponsor academic conferences such as ACM IMC, ACM CoNEXT and TMA, and we collaborate with academic researchers at CAIDA, RIPE NCC, M-Lab, the Internet Society, IIJ, Georgia Tech, and other institutions.

Our measurement platform, Probe Net, collects more than 50TB of ping, trace route, BGP and DNS data every week from over 1,300 servers around the world. As a summer research intern, you'll be a full member of our research team and own one well-scoped research project on that data. We scope each project so it can lead to a publication at a venue such as IMC, PAM or TMA if the results show promise.

• Geolocating hard prefixes. Some prefixes don't answer probes, sit behind anycast, or publish geofeeds that are wrong.
• Claimed vs. measured location. Find the VPN exit nodes whose advertised location is physically impossible given measured latency.
• Topology from imperfect trace routes. Map anycast deployments, router-level topology or submarine cable paths from incomplete, asymmetric paths.
• IPv6 ld target lists and inference methods for an address space that can't be scanned exhaustively.

We'll agree on your exact project with you before the internship starts, based on your research interests. Check out (Use the "Apply for this Job" box below). for examples of our work.

• Drive your project end to end: design the measurements, run them on Probe Net and public platforms such as RIPE Atlas, analyze the results, and validate them against ground truth.
• Work with our data in Big Query at full scale, not on a sample.
• Measure every claim you make about our data in IP addresses against ground truth, not with anecdotes.
• Present your results to the research team and the company, and work on a paper submission with the research team after the internship.
• Ensure that your measurement method works reliably and put it into our production pipelines.

• Currently enrolled in a PhD program in computer science or a closely related field, with research in Internet measurement, networking or network security. We don't consider applications from Bachelor's or Master's students.
• Hands‑on experience with Internet measurement data. You've run measurements yourself (scans, trace routes, RIPE Atlas, DNS), or analyzed large datasets such as BGP tables, trace routes or DNS data in your research.
• Solid knowledge of Internet fundamentals: BGP, IP addressing, IPv6, DNS, anycast, and the pitfalls of trace route analysis.
• Strong Python or Go, and SQL.
• Statistical care. You know how to validate a result and spot a measurement artifact.
• Clear written and spoken
  
  English.
• Available for at least three months between May and October
  2027.

• A publication at ACM IMC, SIGCOMM, CoNEXT, PAM, TMA, NSDI, USENIX Security, NDSS, IEEE S&P or ACM CCS, or in ACM SIGCOMM CCR or IEEE/ACM Transactions on Networking.
• Prior work on IP geolocation, VPN or proxy detection, anycast, Internet topology,or IPv
  6.
• Experience with Big Query or other large‑scale data tools.

We're spread across the globe. The whole company meets on a monthly all‑hands call and the research team meets weekly. You'll have a dedicated mentor for your internship who will be available for regular or ad‑hoc meetings. Everything else happens asynchronously in Slack, Git Hub, and Linear, so you choose the hours when you do your best work. That only works with a high level of autonomy and ownership.

You'll set your own direction, and no one will break your work down into tickets for you.

• A paid internship of at least three months between May and October
  2027.
• A research project with a publication goal, mentored by our research team.
• Access to Probe Net and our full measurement archive.
• A 100% remote team with flexible working hours.
