Hi David, Thank you for the feedback. Postal code accuracy: Please email me directly at abdullah@ipinfo.io with your IP address. I'll investigate why we're not matching the WHOIS data and update the geofeed priority scoring if needed. Dual-stack support: The website is dual-stacked. We're currently exploring how to display both IPv4 and IPv6 information simultaneously when you visit ipinfo.io/my - this feature is in the ideation stage. For our API service, we provide full dual-stack support: ``` api.ipinfo.io/ip v4.api.ipinfo.io/ip v6.api.ipinfo.io/ip ``` Please send me an email with your IP address and I'll look into the postal code issue. — Abdullah | DevRel, IPinfo
