• ns-aws.nono.io now has an IPv6 address, 2600:1f18:aaf:6900::a
• You can use sslip.io's DNS servers (ns-aws.nono.io, ns-azure.nono.io, ns-gce.nono.io) to determine your public IP address by querying the TXT record of the root domain. If you're curious about your public IPv6 address, use the DNS server ns-aws.nono.io, for it has both IPv4 and IPv6 addresses:
