Feedback Request – Embedded Child Protection Solution for Telcos (Academic Research)
by evabouchard38＠gmail.com 27 Jun '25

27 Jun '25

Hi all, I'm part of a postgraduate team at Dublin City University working with Chirp, a startup developing real-time, embedded child-protection software for telecom operators. The solution analyzes data traffic on children’s devices to block harmful content and alert parents to risks such as grooming, cyberbullying, or self-harm — all while respecting privacy and working natively within telco infrastructure. As part of our MSc practicum, we’re seeking feedback from telecom and network professionals on the commercial, technical, and regulatory feasibility of such an approach. Would you be open to completing a short, 10-minute questionnaire? 🔗 https://dcusurveys.qualtrics.com/jfe/form/SV_8oBhWiZMRrUh1zM We’d be very grateful for your insights. Happy to follow up with more technical or contextual details if helpful. Thanks in advance for your time! Best regards, Eva Bouchard

It must be preactivated on services used by a minor ( sim card basically) There is opt in/out and larger providers are required to offer solutions that allow parents to control various categories in some way or another, all for free. You may offer add ins at a cost , such as additional blocking categories, security services and whatever else you can dream up. Brian

IPv6 native percentage (end user perspective)
by Forrest Christian (List Account) 20 Jun '25

20 Jun '25

I see numerous statistics from Google and similar sources that indicate the percentage of end users who are IPv6 native. What I'm missing are statistics going the other way - what percentage of sites (or endpoints that customers regularly connect to) are IPv6-native, from a total traffic perspective? That is, if I switch to IPv6 on my eyeball network, how much of my existing traffic will I have to CGNAT in some way to reach the IPv4-only network? We have sufficient IPv4 address resources to stick with IPv4 for the foreseeable future. However, at some point, the percentage of traffic using IPv6 becomes so high that the reasons not to move become less significant. For example, the CGNAT box becomes significantly smaller, as most of the traffic should flow around it on IPv6. -- - Forrest
