Wow, almost thirty years on the internet and learned a new thing today.

I often wanted hexadecimal IP4 addresses because the standard format is hard to type and some octets in decimal expand to three digits. However seeing it in action and requiring the "0x…" prefix has made me less enthused:

    ping 0x0a000101
    ping 0x0a.0x00.0x01.0x01

Frankly that sucks, no wonder it never caught on. Something shorter with a fixed length like the below would have made me happier, though the ship sailed decades ago:

    ping 0a00.0101
