[Sergey Ulanov, 2015/11/11 21:10:02]

Don't really need to return bool here. rtc::IPAddress has null/nil value (see
IsNil()). So you can return rtc::IPAddress value

+                                rtc::IPAddress* ip_address) {
+  if (ip_address_number.size() == net::kIPv4AddressSize) {
+    uint32 address;

[Sergey Ulanov, 2015/11/11 21:10:02]

Please change this to uint32_t

+    memcpy(&address, &ip_address_number[0], sizeof(uint32));
+    address = rtc::NetworkToHost32(address);
+    *ip_address = rtc::IPAddress(address);
+    return true;
+  }
+  if (ip_address_number.size() == net::kIPv6AddressSize) {
+    in6_addr address;
+    memcpy(&address, &ip_address_number[0], sizeof(in6_addr));
+    *ip_address = rtc::IPAddress(address);
