Update script EveryDNS V0.2

The version 0.2 of EveryDNS
update script now uses curl instead of wget to update your ip. There is
now an additional check to make sure that the update of the ip was
successful. You need to create /tmp/oldip.everydns it’s a temp file
were it checks if the ip has changed. You can download version 0.2 of
EveryDNS update script here or copy the code:
