Re: public address

Hello Peiwai,

dotted decimal notation shows 32 bit IPv4 addresses as a.b.c.d

so between two dots . you can see a number betweeen 0 and 255.

301 in third byte does not fit in 8 bits and so answer 5 is not a valid IP address, regardless of being public or private

Hope to help

Giuseppe
