so we talked a little bit earlier about a default gateway. But let's just look at that one more time, so that will be ableto more fully understand it. We're talking about our default gateway. We're talking about where our computer goes to as its next step. Where goes to get out of our network? Our default gateway is typically in our home environment. It's going to be set
as a router for our computers to use so it can
get out of our network. We have our network here, has our pen, and we have our door default. Gateway is what
can be what sits at our doors or what our gateway is our next step to get out. We have our computer over tablet, and they both have their default gateway set to our router
because that's their next step to get out of here. They go out through there
router as our default gateway.
But there are other times when you may not set your router is your default gateway. Let's say you are using a proxy server, and a proxy server is going out to the Internet for you and that proxy server has some routing capabilities inside of it. Um, set up on that server
and you don't want your computer to go directly to the router,
possibly for security reasons.
So you have it set up so that you're still inside your network here, but your default gateway is going to be this router here, for all the
computers and tablets inside of your network
is going to be that proxy servers a way out
just because we have a router in our environment, just because that's the way to get out of our network doesn't necessarily mean that that final door out of our network is going to be every single computer's default gateway. Our default gateway is just our next step that we want our computer to go to before before it tries to get out of our network.
We may have firewalls set up.
We may have our different proxy server's set up. All of these. We may have different places where we implement different default gateways for our computer, as extra security means extra layers for us to go through before we can just jump out
So just remember that our default gateway is going to be that next step that our computer goes to when it's searching for other computers or searching for a way out,
and it can be set statically or dynamically. We can go on our computer and change the information, set our static i p address and are set statically our default gateway. Or we can have that set automatically through D A, C p
that a lot of times safer are router. We may see default in gateways ending with, like a 0.1 at the end, as because it may have been the first
object the first network network type computer that was put on that network. But not always. Our default gateway can be any address on our network, but again, it has to be an address within our network.
If we're using 1 92.1 68.1 dot one,
our default gateway cannot be
1 87.16 dot 3.75 because that address
is not in our and we have a sudden that mask of 2 55 to 55 to 55 0 That address is not in our network here, so we have to make sure that whatever our default gateway is, it is within our network. It's with in our ability to reach without
having to go through a router.
