		Properly speaking, a wildcard record's scope is limited to a single zone, since, by definition, a wildcard record never matches any name that really does exist in the zone, and thus will not match any (non-wildcard) delegation of a portion of the namespace from a parent zone to its child.
		(Wildcard NS records, while theoretically possible, have sufficiently bizarre semantics that it is probably best to limit their use to torture-tests of DNS software.) So, at first blush, it would seem that the administrator of a zone is free to use wildcards without worrying about effects which this might have on the zone's delegated children.
		We hesitate to recommend a flat prohibition against wildcards in "registry"-class zones, but strongly suggest that the burden of proof in such cases should be on the registry to demonstrate that their intended use of wildcards will not pose a threat to stable operation of the DNS or predictable behavior for applications and users.

		This is in part because, as defined in RFC 1034, wildcard behaviour is not what people generally expect, particularly the interactions between wildcards and MX records.
		With djbdns, in addition to checking for wildcards at the current level, the server checks for wildcards in all enclosing superdomains, all of the way up to the root.
		In other words, if there is a MX record for ".example.com", and an A record* (but no MX record) for "www.example.com", the "correct" response to a MX request for "www.example.com" is "that doesn't exist"; the actual response with Microsoft's DNS server and MaraDNS is the MX record attached to "*.example.com".

	DNS Made Easy!
		Wildcard Records give you the ability to map all (or a section) of the records in your domain to one IP.
		If you create a record that is part of your domain (and inclusive of the wild card set) then only that record is directed to the other IP and everything else will goto the Wildcard record.
		The name field of an MX record contains the host name which appears in the e-mail address, and the data field contains the hostname of the server to which the mail should be delivered.

	Setting up wildcard subdomains on Apache \| AllYourTech.com
		Wildcard subdomains are useful for a variety of reasons.
		To do this, you'll need to create what is called an "A record," which is short for "address record." As the name implies, "A records" tell what IP address a host is pointing to.
		Either way, you'll need to be patient because DNS settings take some time to propagate throughout the Internet (expect at least a few hours for this change to take effect).

		A new attack using DNS cache poisoning has raised concerns about "pharming," a next-generation phishing scam in which malware or DNS hacks are used to invisibly redirect victims to spoofed web sites.
		DNS cache poisoning injects false information into DNS servers, which route Internet traffic by matching domain names with IP addresses at web hosts, allowing hackers to redirect users to bogus web sites.
		In Saturday's attack, a known vulnerability in Symantec firewalls was exploited to change information on a small number of local DNS servers, sending requests for Google.com, eBay.com and Weather.com to a trio of hacker sites (7sir7.com, 123xxl.com and abx4.com) that attempted to install spyware on vistors' computers.

		Wildcard SSL cert is supported by Microsoft, starting with IIS 5 (I think it works with IIS4 as well, but not tested).
		The catch here is that each wildcard SSL cert is bind to a unique IP address, and it's not really working with host header.
		On the other hand, for wildcard SSL site, you basically don't need host header already as the SSL binding is tight to the website IP address.
