Static IP address entry is confusing

[mtsec]

Ubuntu Server 18.04.1 LTS

There appears to be a validation bug when entering a static IP address during the installation of Ubuntu Server. This bug presents itself when there is no DHCP server present on the network.

See the attached screenshot. The mentioned IP address is contained in the subnet, although the validation error appears. None of the combinations I tried seemed to function, so this might be a regression error.

Please conduct some test scenarios to this section of the installer.

These errors prevent the installation to continue.

We should probably think about how better to allow entry of ip addresses. This isn't a but per se -- but it's certainly confusing.
