Confused even through google what to do. We had to get a 2nd NEW IP address to run a security camera to our mobile phones and extra like $5 a month.

But we have multiple devices 10+ (sticks/computers etc.) in the home. Right now we have going skype/facetime calls 3 people on one computer + minecraft! + 3 computers all at the same time. Would a 3rd IP address help? Stronger processor computer?? We have 300+mb devided by the 10+ devices + right now 3 computers + 3 calls and minecraft on 1 computer.

Obviously we can't NOT be on our devices summer coming up the minecraft/skype computer kid will be super busy online.



I'm so confused on what we need to do thanks!

IPv4 can support like 254 different addresses, I am not sure what you mean.

Isn't there 256 0-255?

0 and 255 are reserved for network/broadcast id

someone smarter than me can probably explain that better

Basically one IP address should be enough for normal internet users in one household.
However you needed dedicated IP address for your security camera in order to access it and it must be static else it would be difficult to find it from the internet.

If you have that many different devices connected to the internet and they all work you must be using either modem or router which has NAT system.
NAT creates each device internal IP address which works withing your internal network (household) but for outgoing connections they use the IP address assigned to the modem or router you are using.
You only need dedicated IP address if you want to directly access one device only, not the 10 different ones behind the modem/router.

For example websites and other servers usually require dedicated IP address to directly access them, same with your security camera.
But no one should be directly accessing your home PC, smart television, phones, game consoles and so on.. So it's better to route all traffic from those out to the net via router/modem which allows you to have only one IP address instead of having multiple ones which could cost a lot in the days of ipv4 at least.

Why are considering buying more IP addresses?
It doesn't speed up your connection.
If you want speed and you use wireless connection then you should look for better wireless router which can handle all of those devices.

Check your router's user manual for 'port forwarding'.

Most consumer routers - if not all - have the ability do what is called port forwarding. This means you put your camera (or whatever) behind your router like all your other home network devices but the router presents the camera to the Internet as if the camera was actually on the router's IP internet address. The key is for the camera to be set to a port that nothing else is using.

Quick 101:

An IP4 internet address looks like this: 64.122.321.54
That would be similar to the address of your router to the outside world in this example.

But on the inside, your router would have another address, like this: 192.168.1.1 (192.168.xxx.xxx is set aside for networks inside a firewall, as is 10.0.0.xxx).

And everything else on your network would typically have an address from say, 192.168.1.2 to 192.168.1.254

Those are IP addresses. However, there is something even more fine grained called a port. For instance a regular web page, http://wrongplanet.net is actually served up on port 80: which is the convention for a web page. So it's really wrongplanet.net:80 (or 104.25.180.27:80). Anyway, your camera also serves up it's web pages (images and video) on a port, on it's web address, on your inside network. Your router can be set to present that unique port as if it is that port of the router's facing the outside world.

So your camera's full IP + port address might be 192.168.1.5:8080 in this example. It would be presented by your router to the outside word as 64.122.321.54:8080 and accessible from anywhere on the Internet.

Unless you are running all your devices flat out and using up all your bandwidth, it is quite erroneous to say that you have 300 mbps / ten+ devices.

In fact, it is highly unlikely that you will use 300 mbps in the foreseeable future unless maybe if you are doing torrents.

Even then, probably not. I think that the majority of home routers are still 100 mbps.

By the way, I have a routable IPv4 /24 block (254 usable addresses) and a routable IPv6 /56 block with 2^72 addresses.

My guess is it's 300mb/s WiFi they are talking about, which is something altogether different.

Ahh. A 300 Mbps wifi connected to a 6 Mbps dsl isn't going to see 300 Mbps at all.
