resolved IP is localhost?

[LeonLanford]

yesterday I encountered something strange (real ip is at the image name)



I encountered this before but when I want to copy the ip, the peer is already gone.

just curious, is someone know a way how to do this?

Heisenbug?

Maybe you have some kind of proxying going on where all traffic is routed over localhost?

I don't have proxy or router here, also I'm directly connected to internet and can make my computer as web server

Just curious because I encountered this 2-3 times already

ah this topic moved from lounge, I thought it's just for fun discussing though

keep in mind people have done silly things and have reverse resolve point to localhost.  I can't remember any who did this (as I've run across some IP addresses who reverse-resolve to localhost), but it is a pretty evil thing to do.  It's definitely possible.  However it's clearly not legitimate.

I'd be on a vigilante to make sure reverse(IP)=forward(IP).  That's the way it should be, but people decide to do funny things with DNS and thus break things...

[LeonLanford]

it's evil thing to do? it can break things? why they're doing that? just for fun or it can increase download speed? can you explain more please?

[boxer4]

For "fun" only.  It should not affect download speeds unless clients do stupid stuff with reverse-resolves.  Most clients shouldn't even bother reverse-resolving, it really does not add much value except for piquing curiosity.

This happened a couple of times to me as well, no big deal in my case that is.
