If the IP address is $192\mathrm{.}168\mathrm{.}100\mathrm{.}101$ with a $255\mathrm{.}255\mathrm{.}255\mathrm{.}0$ subnet mask, a valid DNS server address is $192\mathrm{.}168\mathrm{.}1\mathrm{.}250.$

If the IP address is $192\mathrm{.}168\mathrm{.}100\mathrm{.}101$ with a $255\mathrm{.}255\mathrm{.}255\mathrm{.}0$ subnet mask, a valid default gateway address is $192\mathrm{.}168\mathrm{.}1\mathrm{.}250.$

A valid IP address is $127\mathrm{.}0\mathrm{.}0\mathrm{.}1$ with a subnet mask of $255\mathrm{.}0\mathrm{.}0\mathrm{.}0.$

A valid IP address is $169\mathrm{.}254\mathrm{.}15\mathrm{.}9$ with a $255\mathrm{.}255\mathrm{.}0\mathrm{.}0$ subnet mask and a default gateway address of $169\mathrm{.}254\mathrm{.}15\mathrm{.}100.$
