| Summary | 0022605: HostAddrToStr6() returns result wrong way round | ||||||||||||
| Description | Attached program tests IP address conversion from string to binary and back, and from a binary constant to a string. On little-endian (x86) systems, HostAddrToStr6() appears to behave the same as NetAddrToStr6(); on big-endian (SPARC) this appears to also affect the IP4 functions. Also affects 2.6.0, not tested 2.6.1. Only tested on Linux. | ||||||||||||
| Additional Information | Also, when an IP4 connection is accepted on a combined IP6+4 socket on Linux an IP6 socket is returned with a peer address such as ::ffff:ab:cd:ef:01. There appears to be a convention in e.g. Linux ping6 that this is rendered as e.g. ::ffff:171.205.239.1, could this be added as an option to NetAddrToStr6()? | ||||||||||||

Regarding the text representation of IPv4 addresses in IPv6 notation see http://tools.ietf.org/html/rfc4291 [^] paragraph 2.2.3 http://tools.ietf.org/html/rfc5952 [^] paragraph 5 actually recommends the mixed notation. |

Thanks for those Ludo. The comment on representation of port numbers in the second reference is particularly apposite. I realised shortly after posting that my comment on big-endian (SPARC) systems doesn't make sense under the circumstances. |
