- * r_addr
- *
- * Quoting RFC 3530, section 2.2:
- *
- * For TCP over IPv4 and for UDP over IPv4, the format of r_addr is the
- * US-ASCII string:
- *
- * h1.h2.h3.h4.p1.p2
- *
- * The prefix, "h1.h2.h3.h4", is the standard textual form for
- * representing an IPv4 address, which is always four octets long.
- * Assuming big-endian ordering, h1, h2, h3, and h4, are respectively,
- * the first through fourth octets each converted to ASCII-decimal.
- * Assuming big-endian ordering, p1 and p2 are, respectively, the first
- * and second octets each converted to ASCII-decimal. For example, if a
- * host, in big-endian order, has an address of 0x0A010307 and there is
- * a service listening on, in big endian order, port 0x020F (decimal
- * 527), then the complete universal address is "10.1.3.7.2.15".
- *
- * ...
- *
- * For TCP over IPv6 and for UDP over IPv6, the format of r_addr is the
- * US-ASCII string:
- *
- * x1:x2:x3:x4:x5:x6:x7:x8.p1.p2
- *
- * The suffix "p1.p2" is the service port, and is computed the same way
- * as with universal addresses for TCP and UDP over IPv4. The prefix,
- * "x1:x2:x3:x4:x5:x6:x7:x8", is the standard textual form for
- * representing an IPv6 address as defined in Section 2.2 of [RFC2373].
- * Additionally, the two alternative forms specified in Section 2.2 of
- * [RFC2373] are also acceptable.
- *
- * XXX: Currently this implementation does not explicitly convert the
- * stored address to US-ASCII on non-ASCII systems.
