What is a Wildcard DNS?
Monday, September 3rd, 2007A wildcard DNS record is a catch all record in a DNS zone that will match all non-existent requests for a domain name. Just like whenever you setup “catch all” or “nobody” email account, that will act as a “catch-all” account for any non-specified or misspelled username, as long as the domain name is correct. Then you will be able to retrieve these messages at the mail account you specify. So Wildcard DNS is just like that but is used on domain aliases of host name. On another wold you can also call it as Catch all Sub domains. (more…)
