New releaseSep 3, 2026
Go library for retryable DNS resolution supporting TCP, UDP, DoH, and DoT with configurable retries, random resolver selection, and arbitrary query types for network reconnaissance.
Based on miekg/dns and freely inspired by bogdanovich/dns_resolver.
Features
- Supports both system default DNS resolvers and user-provided ones
- Retries DNS requests in case of I/O errors, timeouts, or network failures
- Allows arbitrary query types
- Resolution with random resolvers
- Compatible with various DNS resolver protocols (TCP, UDP, DoH, and DoT)
Using go get
$ go get github.com/projectdiscovery/retryabledns
After this command retryabledns library source will be in your $GOPATH
/etc/hosts file processing
By default, the library processes the /etc/hosts file up to a maximum amount of lines for efficiency (4096). If your setup has a larger hosts file and you want to process more lines, you can easily configure this limit by adjusting the hostsfile.MaxLines variable.
For example:
hostsfile.MaxLines = 10000 // Now the library will process up to 10000 lines from the hosts file
Example
Usage Example:
package main
import (
"log"
"github.com/projectdiscovery/retryabledns"
"github.com/miekg/dns"
)
func main() {
// It requires a list of resolvers.
// Valid protocols are "udp", "tcp", "doh", "dot". Default are "udp".
resolvers := []string{"8.8.8.8:53", "8.8.4.4:53", "tcp:1.1.1.1"}
retries := 2
hostname := "hackerone.com"
dnsClient, err := retryabledns.New(resolvers, retries)
if err != nil {
log.Fatal(err)
}
ips, err := dnsClient.Resolve(hostname)
if err != nil {
log.Fatal(err)
}
log.Println(ips)
// Query Types: dns.TypeA, dns.TypeNS, dns.TypeCNAME, dns.TypeSOA, dns.TypePTR, dns.TypeMX, dns.TypeANY
// dns.TypeTXT, dns.TypeAAAA, dns.TypeSRV (from github.com/miekg/dns)
// retryabledns.ErrRetriesExceeded will be returned if a result isn't returned in max retries
dnsResponses, err := dnsClient.Query(hostname, dns.TypeA)
if err != nil {
log.Fatal(err)
}
log.Println(dnsResponses)
}
