Block an Attackers' IP Address with Express: does not work

At least on my machine it does not work i mean.
if i console.log(req.socket.remoteAddress)
it return that: ::ffff:127.0.0.1
Actually i can find the same info with the much simpler console.log(req.ip)
, but maybe behind the scene it s not as efficient as the previous one, i don t know...
so to bloc the localhost ip i used this solution
app.use((req, res, next) => { const sp = req.ip.split(':') if(sp[sp.length -1] === '127.0.0.1'){ const err = new Error('Forbidden') etc .............................................
That works.

This is a good point, due to ipv6 local ip address may differ per machine and machine setup. I'll address this in the next update
