- I thought of one more addition to this text and I decided it was worth adding.
- I wanted to visit
- the Hackersclub Library, but the proxy at the same site that inspired me to
- write the first part
- of this text wouldn't let me visit 'www.hackersclub.com', so I went to
- 'hackersclub.com'(no 'www.')
- and I managed to visit the site, unfettered by the fickle proxy, with the idea
- below.
-
- As you can see, the banned name has a 'www' in it and the non-banned name is
- just the domain -- no
- 'www' involved. Think about 'www.hackersclub.com'. The 'www' machine is simply a
- subdomain of
- 'hackersclub.com'. So, leave the 'www' out! What I imagine many sysadmins do is
- ban the 'www.'
- section of a given domain and not ban the whole domain. Banning one subdomain
- (the 'www' subdomain)
- will *still leave the main domain and other non-banned subdomains able to be
- contacted!*
-
- In fact, you can connect to most websites with just the domain, no 'www.'
- needed, For example, to
- visit the AltaVista search engine I could visit 'altavista.com' instead of
- 'www.altavista.com'.
-
- Both 'www.hackersclub.com' and 'hackersclub.com' resolve to the same IP --
- 199.227.88.143. So if
- 'hackersclub.com' is let through and 'www.hackersclub.com' is not let through,
- then it is a good
- bet that the proxy bans names, and does not resolve IPs and ban the IPs (since
- the IPs are the same.
- Knowing that fact might come in handy later...)
