Horizon doesn't validate IPv4 settings on Manual Network configuration [1.0rc2]

I can put any value I want, and Horizon will let me proceed, not validating the fields or trying to configure an interface and then ping the chosen DNS server and/or Adélie's repos as a sanity check. I have configured:

  • IP: 225.999.999.222
  • Netmask: 255.255.255.0 /24 (default)
  • Gateway: 255.255.255.111
  • DNS: 9.9.9.9 (default)

And Horizon just let me hit Continue (F8) without signaling any error.

  • There is no 999 in dotted-decimal IPv4 addresses
  • The IP is in the multicast address range (even if the other address bytes were valid).
  • The gateway isn't on the same network as the IP
  • The gateway is in Class E address space
