Jul 16, 2010 · Each network host has a default route for each network card. This will create a 0.0.0.0 route for such card. The address 0.0.0.0 generally means “any address”. If a packet destination doesn’t match an individual address in the table, it must match a 0.0.0.0 gateway address. As other answers have covered, 0.0.0.0 is a legal and valid for some purposes IP address. If all values in a range are legal values, then any flag items you want to define must come from somewhere else. In the Internet Protocol Version 4, the address 0.0.0.0 is a non-routable meta-address used to designate an invalid, unknown or non-applicable target. This address is assigned specific meanings in a number of contexts, such as on clients or on servers. Apr 23, 2020 · What 0.0.0.0 Means In short, 0.0.0.0 is a non-routable address that describes an invalid or unknown target.

@thecarpy, yes, but that doesn't put the 0.0.0.0 address in the source or destination address of any packet, it only tells the host to listen to anything. The OP is actually trying to use the address as the destination address for actual packets, and that is not allowed.
This is most likely a firmware bug, but the only situation I've heard of that -sources- packets from 0.0.0.0 is RARP (reverse ARP) which sends out requests from an all zero MAC to find its IP address. This used to be a component of diskless boot once upon a time but hasn't been seen in quite a while.
Likewise ftp 0.0.0.0 (so it's not some telnet app weirdness). Here's some output to amuse those that still think localhost and 0.0.0.0 are always different: ~ $ ping 0.0.0.0
