Express req.ip is returning ::ffff:127.0.0.1 about node-ip HOT 6 CLOSED

I'd suggest checking out https://github.com/whitequark/ipaddr.js

_.isEqual(ipaddr.process('::ffff:127.0.0.1'), ipaddr.process('127.0.0.1'))

from node-ip.

I had the same issue, went ahead an forked the repo, fixed, and waiting on a merge.

ip-1.0.1 still have problem with transition ipv4 address

ip.isPrivate("::ffff:127.0.0.1") return false

from node-ip.

Hmm, weird, I'd not taken a look at that method before, had just assumed it converted the passed IP address and verified from there.

Seems that method is using regular expressions to do validation, which is fine for IPv4 but IPv6 is a bit more volatile in parsing. Basically it works, but only for each variation that get's manually added.

Try this: npm install https://github.com/bryanwayb/node-ip.git

Also, my PR had been closed, but there's a few reasons to open a new one. Will reference it here once I've done so.

New pull request with the fix is #38

from node-ip.

This has since been fixed in version 1.0.2.
