| Dec 29, 2014 at 16:48 | comment | added | cde | @tonny that's because POSIX inet_addr() returns -1 for invalid values, which loops around to 255. The newer routine, as mentioned in the Linux man page, has better error handling. | |
| Dec 29, 2014 at 16:04 | comment | added | Tonny | In Windows XP (and before that) the function WILL accept invalid octal numbers and still attempts to convert them. This can lead to very non-obvious behavior. As of Vista invalid numbers are treated as domain names and Windows will attempt to do a DNS lookup for these. Which is pretty odd behavior too, but that will at least not cause any problems. | |
