IP addressing

my n/w has /26 subnet, IP range is 10.36.27.64 to 10.36.27.127. Now i want to upgrade to /24 subnet, then IP range will be 27.0 to 27.255.

Can i use same default gateway i.e 27.127 for all hosts? as changing only subnet mask on all hosts & switch interface. Pls suggest

Thanks

Ramesh

Re: IP addressing

Ramesh,

The gateway needs to be in the same subnet as the clients that is servicing.

If you decide to keep the subnet mask of /26, only the clients within the .64 to .127 range will be able to use .127 as the gateway.

If you decide to change the subnet mask to /24, clients within the .1 to .254 can use the .127 as the gateway.

Re: IP addressing

Hi There

Yes, no problem. You can use any of the 254 available IP addresses on the subent as the default gateway.

Most networks I have come across appear to use either the first (.1) or last (.254) available IP address as the default gateway, but again this not a requirement but rather a standard the the Net Admins appear to adhere to.

Best Regards,

Michael.
