Lecture Assignment 7

Due at the start of class, Friday, September 30.

Please submit answers to these questions either as a hard copy (typeset or handwritten are OK) or by email to jteresco AT siena.edu by the start of class. Please use a clear subject line when submitting by email (e.g., CS 180 Lecture Assignment 7, Joe Student). We will discuss these questions at the start of class, so no late submissions are accepted.

1. Use nslookup (it exists on Windows, Macs, Unix) to find the IP addresses of www.yankees.com and www.redsox.com. What does this tell you about whether the mapping of names to IP addresses is unique?
