Interesting. We indeed don't have anything explicit to do this. Actually the IP address (IPv4 or IPv6) *is* internally in binary formay and there's an implicit cast from address to binary that does nothing more than a memcpy(). If you pass the address to something that consumes a binary type on input, it will be automatically cast to this type. For example, if used with a binary stick-table it should automatically cast. Could you please provide an example of how you're trying to use it where you'd like to get the binary format that it does not propose ? That might help to figure if we could for example insert a dummy conversion in between to force the cast, or any such a thing. Willy
