I have an ACL question. I'm trying to set up an acl that will restrict 1 computer to accessing ONLY a website such as UPS.com. On doing an nslookup or Whois for ups.com I find www.ups.com answers to these IP addresses. 220.127.116.11
However, browsing to UPS.com does not necessarily connect to these IP addresses. It seems UPS.com is using some load balancing feature where it (ups.com) could resolve to several different IP's hosted it seems by akamai.
What is the best way to establish this lock down? Machine should only get to ups.com, however, UPS.com is not easily resolvable.
