Is this by chance relevant to iplocation.net? Baseball related? On Thu, Sep 25, 2025 at 1:44 PM Yang Yu via NANOG <nanog@lists.nanog.org> wrote:

Questions for folks ingesting geofeed,

what do you use for address validation? Are non-ASCII characters supported, especially in City field? e.g. 부산 vs Busan What happens when Region field is empty? discard the line / use Country only / try to use Country + City (which may not be unique) Common parsing / validation errors?

Thanks,

Related reminder that the IAB is holding a workshop on IP Geolocation – with statements of interested due at the end of this week. For more info: https://www.iab.org/announcements/call-for-papers-iab-workshop-on-ip-address... Call for Papers: IAB Workshop on IP Address Geolocation (ip-geo) 17 Jul 2025, 6:42 p.m. This workshop aims to understand the current use cases for publishing, discovering, and consuming IP address geolocation data. Workshop Description This workshop aims to understand the current use cases for publishing, discovering, and consuming IP address geolocation data ('IP-geo' hereafter). It will also explore areas for improvement, both in ways to update or replace IP geolocation mechanisms, and to consider mechanisms that satisfy the use cases without relying on IP addresses. The IAB seeks short position papers on the topics listed below. This list is non-exhaustive and should be interpreted broadly. * Today's Use Cases: How is IP-geo data used today? In particular, what are the root challenges, technical needs, or business needs that IP-geo data is being leveraged to address? * Gaps and Problems: What are gaps or problems with the current approaches being used by industry? Are there preferences for particular file types? How effective are current approaches? What are the impacts on user privacy? * Future Opportunities: If we re-designed technical solutions to address the motivating use cases, what would those solutions look like? Are there alternative approaches that can avoid the gaps and problems we have today? Is there value in conveying other information in addition to or instead of geography, such as type of last mile network connection? All inputs submitted and considered relevant will be published on the workshop website. The organizers will issue invitations based on the submissions received. Sessions will be organized according to content, and not every accepted submission or invited attendee will have an opportunity to present; the intent is to foster an active discussion and not simply to have a sequence of presentations. A workshop report covering all submissions and the workshop discussion will be published afterwards.

With this real but anecdotal data point, I would suggest the results of having various non-ASCII or absent fields will vary by organization that ingests your 8805 feed. Beyond that, I have no solid data. -----Original Message----- From: Yang Yu via NANOG <nanog@lists.nanog.org<mailto:Yang%20Yu%20via%20NANOG%20%3cnanog@lists.nanog.org%3e>> Reply-To: North American Network Operators Group <nanog@lists.nanog.org<mailto:North%20American%20Network%20Operators%20Group%20%3cnanog@lists.nanog.org%3e>> To: North American Network Operators Group <nanog@lists.nanog.org<mailto:North%20American%20Network%20Operators%20Group%20%3cnanog@lists.nanog.org%3e>> Cc: Yang Yu <yang.yu.list@gmail.com<mailto:Yang%20Yu%20%3cyang.yu.list@gmail.com%3e>> Subject: RFC8805 geofeed validation Date: Thu, 25 Sep 2025 12:43:42 -0500 Questions for folks ingesting geofeed, what do you use for address validation?
