DNS is a global system for translating IP addresses to human-readable domain names. When a user tries to access a web address like “example.com”, their web browser or application performs a DNS Query against a DNS server, supplying the hostname. The DNS server takes the hostname and resolves it into a numeric IP address, which the web
The SRV record contains more information than the typical DNS record as it contains specific information that can be used to locate a specific resource at an address. This is an example of what an SRV appears like in a typical BIND-style zone file: P/Invoke to the DnsQuery function and pass DNS_TYPE_SRV. An example can be found in this excellent post by Ruslan. I reproduce the code below in case the link breaks, but emphasize it is taken directly from his blog. Aug 05, 2016 · A drawback of SRV Records is that it assumes clients know the correct DNS domain to use as the query target. Without any further information, the client's options includes using their own DNS domain and the name of the security domain in which the client operates (such as the domain name associated to the Kerberos REALM the client refers to). SRV Lookup - Check DNS SRV Records of Domain About SRV Lookup SRV Lookup will list SRV records for a domain, SRV record is a specification of data in the Domain Name System defining the location, i.e. the hostname and port number, of servers for specified services. Jun 05, 2012 · I also tried to DNS query tools on the Internet. No results. So how can I check if the ISP has done it properly or if there are any other SRV records created under the domain. BTW. I tried the same query against compaies, such as Mcrosoft and HP. No SRV records either. What did I do wrong? I even tried to set DNS server to 4.4.4.4 or 8.8.8.8 > > >
Jun 11, 2020 · DNS SRV is an extension of the standard DNS server specification (independent from SIP, as per RFC 2782). SRV (Service Record) is a type of entry a network administrator may put into the DNS server. A DNS SRV request is used to get one or more IP addresses of servers, each one having its own weight, priority and possible port.
Configure DNS A and SRV records. Update your DNS nameserver to resolve a service name, such as myservice.example.local, to one or more hostnames and ports via SRV records. Those hostnames should resolve to IP addresses using A records. Add DNS A records that resolve multiple hostnames, such as host1, host2 and host3, to different IP addresses.

DNS analytical logs are not enabled by default, and typically will only affect DNS server performance at very high DNS query rates. For example, a DNS server running on modern hardware that is receiving 100,000 queries per second (QPS) can experience a performance degradation of 5% when analytic logs are enabled.
