The `-ip` parameter for server mode failed to accept IPv6 addresses,
returning errors like "too many colons in address" or "Invalid IP address".
Root cause: The code concatenated IP and port directly (e.g., "2001:db8::1:8888"),
which is invalid for IPv6. IPv6 addresses must be bracketed: "[2001:db8::1]:8888".
Changes:
- Added formatListenAddress() helper function in utils.go to properly format
listen addresses for both IPv4 and IPv6
- Updated IP validation in ethr.go to accept bracketed IPv6 addresses
- Updated TCP and UDP servers in server.go to use the helper function
Behavior:
- IPv4: Works as before (e.g., "127.0.0.1:8888")
- IPv6: Now works correctly (e.g., "[::1]:8888")
- Empty IP: Works as before (":8888" for all interfaces)
Backward compatibility: Fully maintained. No changes to client behavior,
protocol, or command-line flags.
Testing:
- IPv4 server binding works
- IPv6 server binding works (with and without brackets)
- IPv6 client-server communication works
- All existing functionality preserved
Fixes microsoft#178
