    Question DNS wild card.....

    I was wondering what's the disadvantage if we set DNS wild card to an account?

    Just curious since I just knew that free DNS management granitecanyon does not allow their user set it.

    I can't really think of any disadvantages - other than that if you are using something other than IP based hosting; if people visit a wildcard address they may get an error message (or worse; somebody elses site).

    Unless, of course, Apache is setup to handle wildcard dns. I believe this is done by adding this line to the VirtualHost:

    Code:
    Host *.domain.tld

    You mean:
    Code:
    ServerAlias *.domain.tld

    There ARE DISADVANTAGES!

    People who hate you or you competitors may submit to search engine urls you DONT want to be indexed.

    we-suck.yourcompany.com
    scam.yourcompany.com

    and others...

    and search engines may index them and display to search engine users...

    VERY BAD! VERY BAD!
