A wildcard DNS record is a record in a DNS zone that will match requests for non-existent domain names. A wildcard DNS record is specified by using a * as the leftmost label (part) of a domain name, e.g. *.example.com. The exact rules for when a wildcard will match are specified in RFC 1034, but the rules are neither intuitive nor clearly ...
The domain name system supports wildcard DNS records which specify names that start with the asterisk label, *, e.g., *.example. [23] [39] DNS records belonging to wildcard domain names specify rules for generating resource records within a single DNS zone by substituting whole labels with matching components of the query name, including any ...
I get the sense, from reading the wildcards part of RFC1034, that Paul was just codifying in an RFC the consequence of how an early DNS server stored its records in memory. Samboy 09:20, 9 October 2005 (UTC) As of MaraDNS 1.2.02, MaraDNS now has the ability to optionally handle wildcards in a more RFC-compliant manner.
For example, if there is both an A and an MX for a name, but the name server has only the A record cached, only the A record will be returned. Usually referred to as ANY (e.g., in dig , Windows nslookup , and Wireshark ).
Wildcard Servers with this feature can publish information for wildcard records, which provide data about DNS names in DNS zones that are not specifically listed in the zone. Split horizon Servers with the split-horizon DNS feature can give different answers depending on the source IP address of the query.
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
The policy has been adopted by all ICANN-accredited registrars.It has also been adopted by certain managers of country-code top-level domains (e.g., .nu, .tv, .ws).. The policy is then applicable due to the contract between the registrar (or other registration authority in the case of a country-code top-level domain) and its customer (the domain-name holder or registrant).
Paragraph 15(e) of the UDRP rules defines reverse domain name hijacking as the filing of a complaint in bad faith, resulting in the abuse of the UDRP administrative process. [9] It becomes difficult to objectively quantify what constitutes subjective “ bad faith ,” resulting in panels often viewing parties’ factual discrepancies as ...
