DnsRip is a simple .Net component for doing DNS lookups. Currently only supports the follow record types: A, AAAA, CNAME, NS, MX, SOA, TXT, PTR, and ANY.
var dnsRip = new DnsRip.Resolver("8.8.4.4");
var results1 = dnsRip.Resolve("google.com", DnsRip.QueryType.A);
var results2 = dnsRip.Resolve("www.yahoo.com", DnsRip.QueryType.CNAME);
var results3 = dnsRip.Resolve("microsoft.com", DnsRip.QueryType.MX);//results1 (serialized)
[{
"Server": "8.8.4.4",
"Host": "google.com",
"Ttl": 216,
"Type": DnsRip.QueryType.A,
"Record": "216.58.192.238"
}]
//results2 (serialized)
[{
"Server": "8.8.4.4",
"Host": "www.yahoo.com",
"Ttl": 242,
"Type": DnsRip.QueryType.CNAME,
"Record": "fd-fp3.wg1.b.yahoo.com."
}]
//results3 (serialized)
[{
"Server": "8.8.4.4",
"Host": "microsoft.com",
"Ttl": 1437,
"Type": DnsRip.QueryType.MX,
"Record": "10 microsoft-com.mail.protection.outlook.com."
}]Also includes a parsing method for normalizing hostnames and IPs. Useful for working with URLs.
var parser = new DnsRip.Parser();
var result1 = parser.Parse("http://www.hostname.com:80");
var result2 = parser.Parse(" http://192.168.10.1");
var result3 = parser.Parse("http://[FE80:0000:0000:0000:0202:B3FF:FE1E:8329]:8080/ ");
var result4 = parser.Parse("random_string");//result1 (serialized)
{
"Input": "http://www.hostname.com:80",
"Evaluated": "http://www.hostname.com:80",
"Parsed": "www.hostname.com",
"Type": DnsRip.InputType.Hostname
}
//result2 (serialized)
{
"Input": " http://192.168.10.1",
"Evaluated": "http://192.168.10.1",
"Parsed": "192.168.10.1",
"Type": DnsRip.InputType.Ip
}
//result3 (serialized)
{
"Input": "http://[FE80:0000:0000:0000:0202:B3FF:FE1E:8329]:8080/ ",
"Evaluated": "http://[fe80:0000:0000:0000:0202:b3ff:fe1e:8329]:8080/",
"Parsed": "fe80:0000:0000:0000:0202:b3ff:fe1e:8329",
"Type": DnsRip.InputType.Ip
}
//result4 (serialized)
{
"Input": "random_string",
"Evaluated": "random_string",
"Parsed": null,
"Type": DnsRip.InputType.Invalid
