The IEM-OS and IED-OS are only configurable with IPv4 addresses. Thus, properly working and valid IPv4 DNS server addresses, to set up the IEM-OS and IED-OS, are required. It might happen that on customer's network configurations a DHCP server provides an IPv6 address for an IPv4 network. In that case, the DNS name resolution does not work anymore.

Ensure that the DNS server always provides an IPv4 address for a properly DNS name resolution.
