This is a perfect script in previous versions, I made update and stopped.
I using changeip.com
:local ddnsuser “user”
:local ddnspass “pass”
:local ddnshost “host”
:local ddnsinterface “vlan1”
:global ddnslastip
:global ddnsip [ /ip address get [find interface=$ddnsinterface disabled=no] address ]
:if ([ :typeof $ddnslastip ] = nil ) do={ :global ddnslastip 0.0.0.0/0 }
:if ([ :typeof $ddnsip ] = nil ) do={
:log info ("DDNS: No ip address present on " . $ddnsinterface . “, please check.”) } else={
:if ($ddnsip != $ddnslastip) do={
:log info “DDNS: Sending UPDATE!”
:log info [ /tool dns-update name=$ddnshost address=[:pick $ddnsip 0 [:find $ddnsip “/”] ] key-name=$ddnsuser key=$ddnspass ]
:global ddnslastip $ddnsip } else={
:log info “DDNS: No change” }
}
