I recently hosted a Minecraft server and I have a problem which is that it uses the private ip so only players connected to the same network can join I want to switch it to be hosting the server on my public IP address so anyone from anywhere can join the server. Can you guys help me with that?

[@mr.liquifier8343]

How does VPNS work

[@mr.liquifier8343]

Also If we run out of public IPs wouldnt we have to add another private IP for IP location so Ur town has an IP then that IP has ur IP identity which goes to you and then that IP goes to ur device?

A few points. Some ISPs hand out private addresses, which mean customers are already behind NAT and so cannot connect to their own network from elsewhere. NAT also breaks some protocols. Also, address classes are obsolete, replaced with classless addresses, where a base address and subnet mask are specified. BTW, according to Vint Cerf, the guy who invented this, 32 bit addresses were only intended to be used for proof of concept, with the final version having a much larger address space. Unfortunately, IPv4 escaped, leaving the world trying to get by with only 32 bits addresses.

[@remetremet]

Primary problem of IPv4 in the begining were classes* - and therefor wasting of resources. Unfortunatelly there is the same situation with IPv6 today - every single device should recieve /64 address block (for what?). So it's still unnecessary wasting of resources. Classes are obsolete for almost 30 years, but it was very bad start.

[@James_Knott]

@@remetremet In the beginning there were no classes. The classes were created to make more networks, of varying sizes, available. Originally, it was just 256 of what became class A networks. Later, address classes were deprecated in favour of classless addresses with a subnet mask. Look up Classless Inter-Domain Routing for more info.

[@dannylck1]

i wish i can understand ~~~~~

[@James_Knott]

@@remetremet One other thing about that "waste of resources". While the idea was it would be impossible to run out, another benefit is security. With the address space so sparsely populated, it's virtually impossible to scan for targets to attack. That/64 block has as many addresses as the entire IPv4 address range squared! To give an idea of how big the IPv6 address space is, there are enough addresses to give every person on earth over 4000 /48s. A /48 contains 65536 /64s. And this is with only 1/8 of the address space assigned to global addresses.

A couple things: Most Linux computers these days use "ip a" to get their ip address instead of "ifconfig". The old command can be installed, but is not always there by default.

At 3:29 you display a graphic showing the hosts and the router, but I am a bit confused as the hosts do not have the same subnet address as the router this is a bit confusing for me because I thought that computers needed to have the same subnet address as the router in order to comincate with it? Is this rule different for public and private IP addresses?

[@PowerCertAnimatedVideos]

I was actually going to explain this in the video..but I didn't want to confuse people. Routers/modems have 2 network adapters. One network adapter will have a private IP address just like the internal devices...same subnet...etc. The other network adapter will have the public IP.

It might be beneficial to explain CGN's next since this is fast becoming the norm for ISP's because of IPv4 shortage. And so your ISP assigned IP would not be public.

[@James_Knott]

I mentioned that in an earlier reply. Of course the answer to this nonsense is to move to IPv6. I have a /56 prefix from my ISP, which provides 2^72 public addresses. On IPv6 a network would normally be /64, which provides 18.4 billion, billion addresses. A /56 provides 256 /64s.

[@blcjck8121]

@@James_Knott Totally agree. Old habits I guess. I've also heard some express fear of not being behind NAT on IPv6 as there's a sense of security in that.

[@remetremet]

@@James_Knott I have IPv6 too (from one of two ISPs), but dual-stack is a must for at least next ten years. Not mentioning that about half of devices in my LAN are IPv4 only (even 2021 bought devices). So pure IPv6 is still far future :-(

[@James_Knott]

@@remetremet Well, some transition method is needed. My ISP also provides dual stack, but on the cell network they use 464XLAT, which converts IPv4 to IPv6 when needed. This means they can have an IPv6 only network, but I don't know if they're there yet. ISPs could also use it. Some ISPs use CGNAT for IPv4 in addition to IPv6.

[@ncpolley]

Ok, question I've always had, if my internal IP address is invisible to the outside internet, how does the information I am requesting return to the right device, and vice versa? If the address only says 123 Parker Drive, how do we know the package goes to me, and not say, my roommate, etc. I'm not asking how this could theoretically be done, because I can imagine a solution. I want to know how it's actually done.

[@swagpants]

the tcp packet contains your devices mac address, and is thus used to return to your device. the network knows which mac address you have based on an arp scan

[@shaNk9x]

Your router has a table saying "Computer with MAC address X is currently assigned IP address Y". As you pass your gateway to the internet (in a home network the gateway is commonly integrated to the router), you are assigned a unique public IP address (unless you are on a NAT network). The router then knows to deliver information designated for IP address Y, to the computer with MAC address X. The router know your MAC address and private IP assocation by doing an ARP request. For example, if your router is 192.168.1.1, and the router wants to know who 192.168.1.2 is, the router will send a request over all ports asking "hey, who has IP address 192.168.1.2? 192.168.1.1 would like to know". If the device is directly connected to the router, it would simply answer "192.168.1.2 is at MAC abc".

Awesome video! However, if the Internet wants to sent a packet to a particular device (hidden private IP) in a home, but all devices in that home have the same public IP, how does the router know to which device it should send that packet?

[@JJFlores197]

There's something called PAT (port address translation) which is more or less an extension of NAT (network address translation). When your phone, for instance, sends a packet to KZbin, the router receives this packet and will forward to KZbin's servers. However, the router will add a port number to the packet so that when the web server sends a response, the router knows which port it came from and will send it to the correct device inside of your network.
