CALL FOR PAPERS
NewGeo 2026
New Directions in IP Geolocation Workshop
Co-located with ACM IMC 2026
Karlsruhe, Germany - Monday, October 12, 2026
https://newgeo-workshop.github.io/
================================================================
IP geolocation -- the ability for a third party to map an IPv4 or
IPv6 address to its physical location -- is a foundational building
block for Internet services, network management and operations,
policy enforcement, security, and regulatory compliance. As the
accuracy and coverage of IP geolocation is becoming increasingly
critical, not only are the underlying mechanisms insufficiently
understood, they are increasingly challenged by architectural shifts
in the Internet and evolving services.
The December 2025 IAB Workshop on IP Address Geolocation surfaced
fundamental open questions about accuracy and integrity, the
limitations of self-publishing mechanisms such as geofeeds
(RFC 8805), and architectural tensions between passive location
inference and evolving privacy expectations, and its report
explicitly recommends further research. At the same time, IPv6
adoption, VPNs and relay services, CGNAT, satellite-based access,
and regulatory frameworks such as the EU's GDPR and Digital Services
Act all challenge current geolocation assumptions.
The NewGeo workshop seeks to provide a focused forum on IP
geolocation to consolidate findings, compare methodologies,
benchmark datasets, build shared infrastructure, bring together
academia and industry, and discuss common challenges and future
research directions. NewGeo 2026 invites original research
contributions that advance our understanding of IP geolocation.
IMPORTANT DATES
---------------
Paper submission deadline: September 6, 2026
Notification of acceptance: September 20, 2026
Camera-ready deadline: October 4, 2026
Workshop: October 12, 2026
All deadlines are 23:59 AoE (UTC-12).
TOPICS OF INTEREST
------------------
We solicit short papers on topics including, but not limited to:
* Measurement and analysis of IP geolocation databases
(e.g., geofeeds)
* Novel active and passive geolocation techniques that
accommodate emerging Internet architectures (VPNs, relays,
cellular and mobile, IPv6, CGNAT, address sharing, etc.)
* Geolocation challenges and approaches for satellite-based and
deep space Internet access
* Ground truth collection methodologies and benchmark datasets
* Artificial Intelligence-based approaches for IP geolocation,
validation, or verification
* Longitudinal studies of geolocation accuracy and database
evolution
* Applications and implications of IP geolocation for content
delivery, regulatory compliance, fraud detection, and
censorship measurement
* Privacy implications of IP geolocation and location inference
* Reproducibility studies of previously published geolocation
measurement work
SUBMISSION GUIDELINES
---------------------
Submissions must be original work not previously published and not
under review elsewhere. Papers should be at most 4 pages in length,
excluding references and an optional one-page appendix. Reviewers
are not required to read the one-page appendix. Papers must be
formatted according to the ACM two-column 10 point font sigconf
style:
https://www.acm.org/publications/proceedings-template
All submissions will undergo double-blind peer review by the program
committee, so please anonymize your submission. Authors must adhere
to the ACM's author guidelines on the use of Generative AI:
https://www.acm.org/publications/policies/frequently-asked-questions
Papers violating the submission guidelines will be desk-rejected.
Accepted papers will be presented at the workshop, and at least one
author of each paper is expected to attend in person. Authors are
encouraged to make their measurement data and analysis code
available to support reproducibility.
Submissions will be handled via HotCRP; the submission URL will be
announced on the workshop website:
https://newgeo-workshop.github.io/
VENUE AND ATTENDANCE
--------------------
NewGeo 2026 takes place on Monday, October 12, 2026, co-located with
ACM IMC 2026 in Karlsruhe, Germany. Attendance is handled through the
