At my job, IP prefixes with prefix length 31 (i.e. they only fit 2 IP addresses) are commonly described at "linknet addresses". Lately I have noticed that this term doesn't appear to exist outside of my company. If I do a Google search for "linknet address" or "link net address", I only find references to an ISP called "Linknet".
Does a term exist to describe this kind of IP prefix?
I'm asking because I'm developing a system where such IP prefixes are treated specially, so I need a term I can use to refer to them. I would prefer if this term wasn't one that was made up internally at my company.
