Another problem with this is that you have to be careful with websites
that have multiple IP addresses. 'ping' does not show these very well as
the destination DNS server will round-robin around them and your local
ISP nameserver will probably just cache one example of the round-robin.
However, the program 'nslookup' which comes with Windows ['dig' is a
better program on linux] shows multiple IP addresses up very well. For
example IBM's website has six IP addresses:
M:\Documents and Settings\Barry>nslookup www.ibm.com
Server: ns1.plus.net
Address: 212.159.11.150
Non-authoritative answer:
Name: www.ibm.com
Addresses: 129.42.20.99, 129.42.21.99, 129.42.16.99, 129.42.17.99
129.42.18.99, 129.42.19.99
