0.0.0.0 is a special "no address" or "any address", depending on context.
If a listening server socket binds to 0.0.0.0 then it listens on any interfaces present, which might be two adaptors with addresses 192.168.something and 10.something, for example. 0.0.0.0 is non-routable and a typical use in traffic would be in DHCP, in which an adaptor doesn't have an address assigned yet and the device sends out a DHCP request from 0.0.0.0 asking to be assigned a proper address. I'd ask for clarification, myself :-) On Mon, 23 Dec 2019, 07:53 Jake Anderson, <[email protected]> wrote: > Hello > > Cross posted > > Out network vulnerability team has reported that there is a traffic between > 0.0.0.0 and LPAR IP. > > Does it mean 0.0.0.0 listen to all address and make server open to internet > ? > > I believe 0.0.0.0 belongs to BPXOINIT(OMVS) > > Regards > Jake > > ---------------------------------------------------------------------- > For IBM-MAIN subscribe / signoff / archive access instructions, > send email to [email protected] with the message: INFO IBM-MAIN > ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
