+// NOTE: All the IPv4 addresses used in this file will be represented in the
+//       CPU order and therefore must *not* be used to initialize LWIP
+//       ip_addr types, unless the HTONL macro is used.
+//
+// Example: Given Nemora UDP collector VIP 172.20.0.197, the
+//   DEFAULT_ADDRESSES_TARGET_IP macro expands to the 32-bit number 0xAC1408C5
+//  (to help the reader: 172 is 0xAC), but with our little endian CPU that
+//  32-bit number is represented in memory as:
+//  0xC5 @ offset 0, 0x08 @ offset 1, 0x14 @ offset 2, 0xAC @ offset 3
+//  Since LWIP uses network order, a correct initialization requires:
+//  ip_addr collector = { .addr = HTONL(DEFAULT_ADDRESSES_TARGET_IP) };
