Steps to reproduce...

1. Build Linux box - Attempted on both Gentoo and Ubuntu 20.04
2. Install Minecraft
3. Assign multiple IPs to an adaptor (192.168.1.2, 192.168.1.3, 192.168.1.4)
4. Attempt to connect to 192.168.1.3 or 192.168.1.4 - doesn't work
5. Attempt to connect to 192.168.1.2 - it works

What I expected to happen...
Bedrock should either bind to all IPs and answer on all IPs, or allow specification of which IP to bind to within server.properties

What actually happened...
Bedrock only binds to the first IP

How this affects the usage of BDS...
On a system with multiple IPs it is ambiguous as to which one Bedrock will answer on.
