Suppose that subnet A has a CIDRized subnet address range of $128\mathrm{.}119\mathrm{.}160\mathrm{.}128/26($hint: $128$ is $10000000$ in binary$)$; Subnet B has an CIDRied subnet address range of $128\mathrm{.}119\mathrm{.}160\mathrm{.}64/26.$We now want a valid CIDRized IP subnet address range for subnet C of the form $128\mathrm{.}119\mathrm{.}160.$x$/26.$ What is a valid value of x$?$
