Hostname issue.

Well, I  have no answer but I need to learn about this stuff, so I have a question ....

If your router is set to 192.168.1.1, with a subnet mask of 255.255.255.255.0 , why would you put your peripheral devices on a different subnet (10.0.128.100)?

Would you expect to be able to ping them?

This is a *genuine* question from a relative novice.

I think you might be confused.

I wanted to have a portable network set-up using the 10.0.128.100 IP address.

My Personal Home network uses 192.168.*.*  (removed numbers)

I am talking about two network situations where the devices are in separate situations.

About your question:

Would you expect to be able to ping them?

Yes.  Provided you have put the same subnet mask on both devices.  I have seen this done on Corperate networks where they use an IP address for wireless devices and LAN devices.

I think you'll find they add a route to allow the different IP address to work, or they use NAT (Network Address Translation) which is effectively what your broadband router does.

This may be part of the switch, or within the devices protocols.

Normally you will have a gateway address, where the device heads if its not an address on the local LAN.

For grahame's example there are 254 address's available, so anything that is 192.168.1. x will be treated as Local, and anything else heads out the gateway and is resolved elsewhere.

If I understand correctly you have a portable network that is attached onto your home network.

Have you tried changing the Gateway address to the 192.168.*.* (pick something that doesn't clash).

This would then mean that anything not intended to be local (ie 10.0.128. x) will go out the gateway which should be your local lan.

Cian,

You need to bridge the two networks together, both the 192 and 10 networks are reserved for internal networking. These will be the internal addresses on your own network, not the outward facing IP assigned by your ISP.

Putting the same netmask will not cause them to be linked, as Mark indicates this is only in reference to the number of ip address available on that subnet. See below, I think it will give you some pointers.

I wasn't confused Cian, so much as curious. Thanks for explaining about your two networks. The comments above seem to be well in line with my own humble thinking, and will hopefully help you reach your goal.

P.S.

Since you know the IPs on your alternative network -- I imagine that you use Address Reservation or no DHCP -- it should be very simple to access them  that way. Interested to know the advantage(s) of calling them by name (lots to learn, here).

I was curious, and cautiously so, to know what would happen if one sends an IP request 'intended' for local receipt out onto the internet, so I did a whois on    10.0.128.100   and got this....

I suppose it doesn't matter much, and they might blame the Albanians anyway, according to your info.
