inline below. Great share btw......
I'll move ahead and address this share even though I have not readied my
return query to the bottom half of your last share...... :) Apologies to
the remaining List members if this discussion is causing problems............

I'm not certain because I've never tested it, but I think on the LAN side
you must use a subnet that would be confined to a single Class C network
when using a consumer router. Using 255.255.0.0 as a subnet mask would
actually be subnetted as a Class B network since only the first two octets
would be the network portion. It could be that a router would let you
enter this type of subnet on the LAN configuration but would not function
as expected.
OK. I understand. I will again attempt to apply a class C network
strategy. Even though the LAN runs very much better using class A with a
full (25.255.255.0) netmask. Even the router is happy at
10.0.0.1/255.255.255.0.
Nice choice on the router btw; I own the very same unit. I wanted a router
with a gigabit switch and tests on Tom's Hardware showed that it could
support a high speed WAN connection as well as many active sessions, thus
making it P2P file-sharing friendly. My previous router would
spontaneously reboot if I had too many active connections due to Kademlia.
It simply wasn't powerful enough to handle the load. Anyway.. back to the
subnets..
Superb, another resource for future router questions....Hayes, now there
are 3 of us!..... :)
I think the only valid choices for a subnet mask when using these kinds of
routers would be one that restricts you to functioning under a single
Class C network. (when I say Class C I mean that when looking at an IP of
AAA.BBB.CCC.xxx only hosts whose first three octets are matching, can
communicate directly) The usable subnet masks are the following....
255.255.255.0 (1 network, 254 hosts)
255.255.255.128 (2 networks, 126 hosts each)
255.255.255.192 (4 networks, 62 hosts each)
255.255.255.224 (8 networks, 30 hosts each)
255.255.255.240 (16 networks, 14 hosts each)
255.255.255.248 (32 networks, 6 hosts each, used with 5 ip accounts)
255.255.255.252 (64 networks, 2 hosts each, what most ISPs assign)
OMG. I did miss this business 2 years ago. So, this is how true "subnets"
- actual seperate channels for groups of PCs get done. Amazing, truly
amazing. I do not fully grasp, but now know which chapters of my book to
re-read..... :)
Now, I just finished trying to use a 192.168.218.x IP series. Maybe
boneheaded, but I used the value of 218 in the 3rd octet just because my
home address is "218." It seemed like a valid way to differentiate "my" LAN
from all of the plethora of 192.168.?.? LANs on planet Earth. The fun
started from this decision. It took, but was slow and glitchy. When I
make a major LAN change to my LAN topography (like an IP address series
choice), should I be using some tool or "reset process" for the winsock
when I make these changes (class A to class C)?
I never did. And still have not. Even though I am back to almost where I
started with some minor address changes.
If you were using a Class C address of 192.168.1.x and a subnet mask of
255.255.255.192 you would essentially be chopping up 192.168.1.x into 4
subnets. There would be a total of 64 ip addresses in each subnet but
since the first and last address of any network are reserved, there are
only 62 usable addresses for your hosts. The same logic can be seen in the
other subnet masks.
I know I'm probably repeating/rephrasing some of what I already said but I
think more examples help me when trying to understand something.
Do not apologize, please! Your examples help draw the mental pictures I
need to grasp these really subtle things. I was working for Xerox back when
this "ethernet" thingy came to be. Thought I had a good grasp. Perhaps
not. It just seems to have gotten so much more complicated - for obvious
reasons! I do appreciate the level of detail.
Best,
