In December, Dokic again played the Australian Open Wildcard Playoff event, where she emerged from the round-robin stage with a 2 – 1 record, subsequently winning through to the final playoff.

Holmgren has posted a 72-56 ( 56. 3 %) regular-season record and a 3-4 ( 42. 9 %) postseason record, including an AFC West Division title ( 1999 ), one NFC Wildcard berth ( 2003 ), four consecutive NFC West Division titles ( 2004, 2005, 2006 and 2007 ), an NFC championship ( 2005 ), and the Seahawks ' first-ever berth in a Super Bowl.

Despite a losing record of 7 – 9, the Blaze got into the playoffs as an AC Wildcard ( the conference's # 6 seed ).

In his first match of the Australian Open Wildcard playoff, he was drawn against reigning Australian Open juniors champion Brydan Klein and had a fiery contest.

Another is called Wildcard which appears to cycle through all of the regular Snoods, and may be used in place of any of them.

The Steelers have swept all divisional opponents twice, in 2002 and 2008 ( going 7 for 7 both times, winning against the Browns in a 2003 AFC Wildcard game and the Ravens in the 2009 AFC Championship ), and the Ravens and Bengals have swept all three divisional opponents once each, the Bengals in 2009 and Ravens in 2011.

In the Wildcard Round they hosted a playoff game for the first time, defeating the Cincinnati Bengals 31-10.

In the 2010 Wildcard Playoff Game against the Kansas City Chiefs, McGahee scored a 25-yard touchdown run late in the 4th quarter that sealed the win for Baltimore.

* Address Prefix List, a DNS record type

A DNS name server is a server that stores the DNS records for a domain name, such as address ( A ) records, name server ( NS ) records, and mail exchanger ( MX ) records ( see also list of DNS record types ); a DNS name server responds with answers to queries against its database.

BIND version 9 was written from scratch and now has a security record comparable to other modern DNS software.

To improve efficiency, reduce DNS traffic across the Internet, and increase performance in end-user applications, the Domain Name System supports DNS cache servers which store DNS query results for a period of time determined in the configuration ( time-to-live ) of the domain name record in question.

* A non-recursive query is one in which the DNS server provides a record for a domain for which it is authoritative itself, or it provides a partial result without querying other servers.

The time for which a resolver caches a DNS response is determined by a value called the time to live ( TTL ) associated with every record.

When performing a reverse lookup, the DNS client converts the address into these formats, and then queries the name for a PTR record following the delegation chain as for any DNS query.

* Sender Policy Framework and DomainKeys, instead of creating their own record types, were designed to take advantage of another DNS record type, the TXT record.

In addition to helping develop TCP / IP and the Domain Name System ( DNS ), ISI contributed to the Net by editing the " Request for Comments " ( RFC ) series, the written record of the emerging network's technical structure and operation, from 1977 through 2009.

Another way of locating LDAP servers for an organization is a DNS server resource record ( SRV ).

* The SSHFP DNS record ( RFC 4255 ) provides the public host key fingerprints in order to aid in verifying the authenticity of the host.

TTLs also occur in the Domain Name System ( DNS ), where they are set by an authoritative name server for a particular resource record.

A TTL value of 86400 would mean that, if a DNS record was changed on the authoritative nameserver, DNS servers around the world could still be showing the old value from their cache for up to 24 hours after the change.

TTL values are " per record " and setting this value on specific records is normally honored automatically by all standard DNS systems world-wide.

A DNS name server is a server that stores the DNS records, such as address ( A, AAAA ) records, name server ( NS ) records, and mail exchanger ( MX ) records for a domain name ( see also List of DNS record types ) and responds with answers to queries against its database.

A DNS zone

However, the allowed formulation of domain names in the DNS root zone, and most other sub domains, uses a preferred format and character set.

Every DNS zone must be assigned a set of authoritative name servers that are installed in NS records in the parent zone, and should be installed ( to be authoritative records ) as self-referential NS records on the authoritative name servers.

However, with only authoritative name servers operating, every DNS query must start with recursive queries at the root zone of the Domain Name System and each user system must implement resolver software capable of recursive operation.

When the DNS resolver gets a PTR ( reverse-lookup ) request, it begins by querying the root servers ( which point to The American Registry For Internet Numbers ' ( ARIN's ) servers for the < tt > 208. in-addr. arpa </ tt > zone ).

This work includes coordination of the Internet Protocol address spaces ( IPv4 and IPv6 ) and assignment of address blocks to regional Internet registries, for maintaining registries of Internet protocol identifiers, and for the management of the top-level domain name space ( DNS root zone ), which includes the operation of root nameservers.

Management of most top-level domains is delegated to responsible organizations by the Internet Corporation for Assigned Names and Numbers ( ICANN ), which operates the Internet Assigned Numbers Authority ( IANA ) and is in charge of maintaining the DNS root zone.

Examples of such mechanisms include DNS zone transfers and file transfer protocols.

DNS provides a mechanism whereby the primary for a zone can notify all the known secondaries for that zone when the contents of the zone have changed.

The contents of a zone are either manually configured by an administrator, or managed using Dynamic DNS.

To do this the name server queries each authoritative name-server in turn, starting from the DNS root zone.

The tree sub-divides into zones beginning at the DNS root zone.

Top-level domains form the DNS root zone of the hierarchical Domain Name System.

Another more effective technique for load-balancing using DNS is to delegate < tt > www. example. org </ tt > as a sub-domain whose zone is served by each of the same servers that are serving the web site.

While RFC 2136 supports all DNS record types ( including zone and user ), it is most commonly used for dynamic hosts.

The Internet Assigned Numbers Authority ( IANA ) is the entity that oversees global IP address allocation, autonomous system number allocation, root zone management in the Domain Name System ( DNS ), media types, and other Internet Protocol-related symbols and numbers.

ICANN also operates the. int registry for international treaty organizations, the. arpa zone for Internet infrastructure purposes, including reverse DNS service, and other critical zones such as root-servers.

The Department of Commerce also provides an ongoing oversight function, whereby it verifies additions and changes made in the DNS root zone to ensure IANA complies with its policies.

The InterNIC project included IP number assignment, ASN assignment, and reverse DNS zone management tasks until December 1997 when the American Registry for Internet Numbers came into operation.

A DNS-based Blackhole List ( DNSBL ) or Real-time Blackhole List ( RBL ) is a list of IP addresses published through the Internet Domain Name Service ( DNS ) either as a zone file that can be used by DNS server software, or as a live DNS zone that can be queried in real-time.
