Where do these network interfaces get their public IP address? Does a router assign it?

[@javiertrujillo5016]

Great job!

[@coloal97]

I love you, man! Best tutorial ever, ¿Anywhere I can pay for this, you deserve it?

[@JuriyBura]

Your appreciation is a best reward for me. Thank you for your kind words 🙂

[@worldtreeboy8712]

can a single interface have multiple ip address?

[@JitenPalaparthi]

very well explained.

[@ragrazila]

awsome! thanks

[@geografiaeducativa2727]

Greetings, a query, what advantages or disadvantages would it have by placing the same IP that a router supplies me for its DCHP service. I simply assign it to myself in the /etc/network/interfaces file to have it as a fixed ip, would that give it more protection in case of attacks on the pc through the router? What difference, advantages or disadvantages would it have in doing it or not. ? Sorry my bad english

[@superknife0512]

Sure, let's discuss, will be happy to help. My email is [e-mail]

[@denisfrolov242]

Hey Jura, I replied to your email. Just to let you know in case if it ended up in the junk))). Cheers!

[@RADIOSCATRACHASUTAN]

The guy is good.

[@jacoblee5648]

3:15 Can anyone explain this ? They are able to send a packet since they are listening on different interfaces they will not be able to establish a connection. I'm a noob for networking. What I don't get it is that how do they send a packet while they are not connected ?

[@JuriyBura]

Jacob Lee - they are connected to the *host*, but not to *the application* since the application is not listening on that interface.

[@yumingui5271]

Hi, juriy, what does the code "const hostname = process.argv[2] || null" for? I have a 502 error and I watched your video and added this code and now my server works. The nginx reverse proxy works well now. I am grateful for your courses. But I have no idea why the piece of code works. Would you like to explain a little? Thanks.

[@JuriyBura]

This code reads the first argument of a program and saves it as a host name. If it doesn't find the first argument, then the host name is null. So if you run your program like:
node main.js localhost
then process.argv[2] is a string "localhost".
Glad that videos helped :)

[@mbigras]
