If first used -> Ethernet.begin(arduino_mac, arduino_ip, dns_ip, gateway_ip, subnet_mask );
I won 2ko space flash with this IP static method, but made a mistake with formating “arduino_mac”.
So I finally reduced my sketch to have space enough with the simple DHCP method ->
Blynk.begin(“token”, server_ip, 8080);
And it works now fine. So it seems Blynk.begin() method makes automaticaly the job about the MAC adresses.
