require('os').networkInterfaces() should return 'netmask' (IPv4) or 'prefixlen' (IPv6)

[ this is so exciting... my first node.js 'issue' ... ]

folks - if you're going to look at an IP address and figure out whether it's on the same subnet, you really need to know network prefix for the address.

looking at http://nodejs.org/api/os.html#os_os_networkinterfaces where we have

{ 
  ...
  en1: 
   [ { address: 'fe80::cabc:c8ff:feef:f996', family: 'IPv6',
       internal: false },
     { address: '10.0.1.123', family: 'IPv4', internal: false } ],
  ...
}

we ought to have:

{ 
  ...
  en1: 
   [ { address: 'fe80::cabc:c8ff:feef:f996', prefixlen: 64, family: 'IPv6',
       internal: false },
     { address: '10.0.1.123', netmask: '0xffffff00', family: 'IPv4', internal: false } ],
  ...
}

already landed in master, see #4743

[mrose17]

thanks... i don't see it on 0.10.12/darwin, but i'm sure i'll see it soon!

[tjfontaine]

it won't be in the 0.10 releases, because it's new it will be in the 0.11 series, if it's not in the latest it will be in the next

[mrose17]

excellent, thanks... it will take me a little while to figure out the release strategy...

@mrose17 Even-numbered releases are "stable". No new API additions, only fixing bugs, etc.

Odd-numbered releases are "unstable". That's where we work on getting things ready for the next stable branch.

v0.10 releases go off of the v0.10 branch. v0.11 (or whatever the current unstable is) come off of the master branch.

After 0.11 will be 0.12. The next stable release after the 0.12 series will be 1.0.
