Dear LwIP developers

For now function `ip4addr_aton` returns 1 for this IP address "192.168.095". This is a bug. 095 is not a valid octal number, and the function should return 0 instead.

In attachment there is a patch that fixes it. There is also "ip4addr_aton_test.c" which performs some tests for this function.

Kind regards,
