I just got back from a 2 week trip away, and I want to start trying to
figure out how to make ssh work again.
I will start off by saying that ssh works fine within my internal home
network - I can easily connect my laptop to my desktop and vice versa.
I want to try and get my laptop to connect to my desktop when I am away
from home, through the internet, via ssh. But before I try and do that,
I figure I need to understand some of the networking fundamentals, so
First, when I left, my router’s internet ip was 184.108.40.206. Now, when
I have just returned, it is 10.214.55.218. This changes just about every
day, as we have to reset our router 2 or 3 times a day on average, and
we get a new ip address every time. However, my understanding was that
66.x.x.x is an internet rout-able ip address, and 10.x.x.x is not, so I
believe that something has been changed by my isp with how they are
assigning ip addresses in the 2 weeks I was gone. When I had the
66.x.x.x address assigned to my domain name
tribaltrekker.ignorelist.com, I could put “tribaltrekker.ignorelist.com”
in the command line of my browser and it would connect to my router
(from inside the network - it never worked outside the network).
However, now with the 10.x.x.x ip address assigned to that domain name,
it doesn’t connect even inside the network.
In any case, I am on a 10.x.x.x network now.
I am trying to figure out what type of network I am on from my isp, and
what the subnet mask might be. I know what the subnet mask is for inside
my home network, just not what it is outside. I figure this will help me
understand what kind of network my isp is providing.
Because my router’s ip address is 10.214.55.218, that means we are on a
subnet controlled by my isp, right? But is that really a “subnet” or is
it called something else?
The “name server” that comes up on the WAN status page of my router is
220.127.116.11. Does that mean that the sub-network I am under provided by
my isp is a class C network? Or is the “name server” something else?
All the google helps for “name server” talk about how a name server is
for translating the human memorable names into a series of numbers,
which seems like a totally different thing than the “name server” listed
on my router’s status page.
Now that my router no longer has an internet rout-able address, how do I
connect my domain name (tribaltrekker.ignorelist.com) to my router? I
assume that is the first step to being able to use ssh from outside my
network. If it is not, is there some other way?
