   I assume the target host is behind a router (with port forwarding set up). Network change is detected via `ip -6 route monitor`. To avoid unneccesary updates, the router's public IPv4 address is locally checked by pinging the address with TTL=1 before obtaining the current one from https://www.ipify.org and triggering an update. The host IPv6 address is directly extracted from route updates.

   Please disable either DHCPv6 on the router or SLAAC on the host so that only one IPv6 address is used.

   Please fill in `$ZONE_ID`, `$RECORD_ID`, `$API_TOKEN` and `$INTF` in `cloudflare-ddns.sh`
