IP Addressing

Question

In the below given network, the source IP address is 10.1.1.10.

Suppose a host X with IP address 192.16.1.97 is connected through two routers R₁ and R₂ to another host Y with IP address 10.1.1.7. Router R₁ has two IP addresses 192.16.1.135 and 192.16.1.110. Router R₂ has two IP addresses 10.1.1.67 and 10.1.1.155. The network mask used is 255.255.255.224. Which IP address should X configure its gateway?

Asthe subnet mask is 255 255 255 224 , i think 

gateway will be 192.16.1.110 ??

Answer 1

R1 is connected with 2 IPs namely 192.16.1.135 and 192.16.1.110.  

X has IP address 192.16.1.97 with 192.16.1.011***** as network id in the last octet. So, the gateway should also have the same network id as 192.16.1.011*****. 192.16.1.110 has the same Network ID and hence should be the gateway for X node.
