I am using:

/sbin/ip -6 addr|grep -v temporary|grep 'scope global'|grep -oE '([0-9a-f]{0,4}:){1,7}[0-9a-f]{1,4}'

to grep my global, non-temporary IPv6 address, that is advertised by my router using NDP.

Now, I would like to report this address to a DynDNS service. Where would I put this script to be automatically executed on the change of the adress?

I think /etc/network/if-up.d is a wrong place since, as far as I understand, NDS might advertise a new address without the interface going down and up. Is there another script hook?

For now, I added a check if anything changed and am calling a cronjob once a minute.
