Thanks for all your hard work! icanhazip.com / icanhazptr.com have been incredibly useful.
Small feature request: back in the day {ipv4,ipv6}.{icanhazptr,icanhazip}.com only had A / AAAA records, but now it seems they have both and thus a simple "curl ipv4.icanhzptr.com" can also give me a v6 address (of course, "curl -4" works). Would Cloudfare be OK with separating them again?
