.. deductions like that are exactly my point! ; ) Concepts like 'broadcast' are really only applicable to a broadcast network - a broadcast network two hosts do not make (I believe it is a yoda quote ; ) -----Original Message----- From: Public <public-bounces@talk.mikrotik.com.au> On Behalf Of Tim Allingham via Public Sent: Tuesday, 9 January 2024 11:45 AM To: MikroTik Australia Public List <public@talk.mikrotik.com.au> Cc: Tim Allingham <tim@tasmanitservices.com> Subject: Re: [MT-AU Public] /31 Deployments for Point-to-Point links Hmm, but if we're being pedantic wouldn't there also be 0 usable addresses in a /31 once network ID and broadcast have been reserved?

/31 is not really a 'subnet' anyway, in the sense that a subnet is really just a conceptual structure for a broadcast domain. More properly, I prefer to call /31 an 'address range' instead of 'subnet'
If we are going to get pedantic, let's call it by its One True Name, which is "prefix length".
All prefix lengths[1] are subnets, all subnets are address ranges, but not all address ranges are subnets.
It's subnets all the way down :-)
