  Wildcard DNS record - Wikipedia, the free encyclopedia
A wildcard DNS record is a record in a DNS zone file that will match all requests for non-existent domain names, i.e.
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.

 java.net: Explorations: Wildcards in the Generics Specification
Wildcards are a recent addition to the generics specification based on the idea that sometimes you don't want to precisely specify the value for a type parameter.
The board game Othello used to have a slogan: "A minute to learn, a lifetime to master." Similarly, wildcards are a fairly small change to the syntax of generics (a minute to learn), yet are one of the more subtle ideas in the generics specification (a lifetime, or at least an entire article, to master).
Once you're familiar with the syntax, we'll move on to talking about the reasons wildcards were added to the specification.

 Internet Architecture Board - IAB Documents
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.

 Providing Compatible Schema Evolution
There are uses of wildcards and type extension that could be used to enable validation of the instances and creation of a new schema.
In this example, because the "last" element definition occurs before the wildcard, an occurance of a "last" element in a document should be attributed to the "last" element definition, and any subsequent non-"last" elements are attributed to the wild card.
A significant problem with wildcard constructs is that it requires the author to either: place wildcards in ever possible extensible spot, or to guess where the extensibility will occur.

 Expanding a Search with Wildcards   (Site not responding. Last check: 2007-11-06)
Wildcards are symbols that, when used in a search, tell the search engine to look for all possible endings to a word.
Using a wildcard symbol, typically an asterisk, you can search for all words that take the form writ*, thus increasing the size of your search results.
The most common wildcard symbols are an asterisk (*) for multiple letters, numbers, or symbols, and a question mark (?) for single characters.

If typed wildcards were treated as the priority for the wildcards, we have satisfied one of the limiting factors to picking the pattern for which we want to execute the template.
It is natural to substitute a date type wildcard instead of a generic wildcard in a pattern where we know a date should occur.

 Examining wildcards and compatible evolution
In a subsequent revision of the specification, the wildcard where extension occurs is replaced with an optional element (optional elements preserve backwards compatibility) and a new Extension element is placed after the optional element.
Given that the wildcard is going to be replaced with an element if the namespace owner makes a change, they can use the targetnamespace and effectively "promise" how they will make changes.
The technique of using an extensibility element with a targetnamespace wildcard has the advantage over other namespace wildcard because it means that a single namespace and related schema can be updated with the new type information and allowing others to retain their ability to extend the instance.

 Using the Right Wildcard Characters in SQL Statements (Inside Microsoft Access 2001)   (Site not responding. Last check: 2007-11-06)
Even if you've mastered using wildcards in queries, you may be in for a shock if you switch to using ADO in your applications.
Rather than using the asterisk (*) and question mark (?) symbols as wildcards, ADO requires that you use the percent sign (%) to match multiple characters and the underscore (_) to match a single character.
Making the necessary adjustments to change DAO wildcards to ADO wildcards may be a simple task, but if you're using ADO wildcards in your code you may prefer to also do so in the query design grid.

By placing this wildcard at the beginning, middle or end of a pattern, you can build a pattern which has the rest of the pattern at one or either end.
It takes the pattern containing wildcards, convert it into a list of matching filenames, and pass that to the program in place of the pattern.
Wildcards will not match hidden files unless the wildcard pattern itself starts with a period.

 ICANN | Announcement | 3 October 2003
VeriSign's wildcard creates a registry-synthesized address record in response to lookups of domains that are not otherwise present in the zone (including reserved names, names in improper non-hostname format, unregistered names, and registered but inactive names).
The VeriSign wildcard redirects traffic that would otherwise have resulted in a "no domain" response to a VeriSign-operated website with links to alternative choices and to a search engine.
ICANN is also aware of communications from Register.com (another large ICANN registrar) and Cigref (an association that represents the 117 largest French Internet user companies) to VeriSign expressing similar concerns, and of the fact that at least three lawsuits have been filed challenging the specific changes introduced by VeriSign.

 Qmail - Wikipedia, the free encyclopedia
As such, mail to non-existent mailboxes (whose domain parts are correct, of course) is accepted by qmail's SMTP Relay server, and qmail generates and sends bounce messages when the non-existent mailbox name is later detected, at the point of actual mailbox delivery.
that as long they support a user-specifiable "address extension" mechanism with wildcarding of some kind, even those other MTAs still have the same problem of mail that cannot be discovered to be undeliverable until after the SMTP Relay server has accepted it, and that thus this merely papers over the problem;
Yet spammers and worms can employ "Delivered-To:" headers to cause mail to be bounced at the point of actual delivery, and thus to send their payloads to targets as bounce messages sent by intermediaries.).

Wildcards are much more powerful and flexible than filename completion, and most shells have their own advanced wildcards that do powerful and sophisticated things.
You can create a wildcard pattern that matches all filenames composed of zero or more digits, but the syntax is different.
