SRV Record Lookup: Check DNS Service Records Instantly
Use HasheTools’ Free SRV Record Lookup Tool to instantly find DNS Service (SRV) records for any domain.
Quickly verify service locations, ports, and priorities for protocols like SIP, XMPP, LDAP, Minecraft, and more, all in one click.
What Is an SRV Record?
An SRV (Service) record is a DNS record type that defines the location of servers for specific services within a domain. It contains information such as:
- Service Name: e.g., _sip, _ldap, _minecraft
- Protocol: usually TCP or UDP
- Priority & Weight: used for load balancing and failover
- Port: identifies the service port (e.g., 5060)
- Target: the hostname of the server offering the service
These records are essential for applications that require automatic service discovery, such as VoIP, chat, authentication, and gaming servers.
Example of an SRV Record
| Record | Type | Priority | Weight | Port | Target | TTL |
| _sip._tcp.example.com | SRV | 10 | 60 | 5060 | sipserver.example.com | 3600 |
This means the SIP service (_sip) uses TCP, runs on port 5060, and the host server is sipserver.example.com.
Why SRV Records Are Important
SRV records make network communication seamless by handling:
- Service Discovery: Automatically locate network services.
- Load Balancing: Distribute traffic based on priority and weight.
- Failover & Redundancy: Define backup servers for reliability.
- Protocol-Specific Routing: Used in SIP, LDAP, XMPP, Minecraft, and Kerberos systems.
Without SRV records, users would have to manually configure hostnames and ports for every service.
How to Use HasheTools’ SRV Lookup Tool
Follow these simple steps to check SRV records online:
- Enter your domain name (e.g., example.com) in the search box above.
- Specify the service type (e.g., _sip._tcp, _xmpp._tcp, _minecraft._tcp).
- Click “Lookup” and get instant DNS SRV record results.
- View all SRV fields, including priority, weight, port, and target host.
This tool queries DNS servers directly for the most accurate, up-to-date results.
Understanding SRV Record Fields
| Field | Description |
| Service | The symbolic name of the desired service (e.g., _sip, _ldap) |
| Protocol | Defines the transport protocol (TCP or UDP) |
| Priority | Lower values have higher priority |
| Weight | Used for load balancing when priorities are equal |
| Port | Specifies the port number used by the service |
| Target | The domain or hostname providing the service |
Common Uses of SRV Records
SRV records are widely used across multiple platforms and protocols:
- SIP (Session Initiation Protocol): Enables VoIP and video calling.
- XMPP (Jabber): Manages instant messaging and chat connections.
- LDAP: Directory service authentication for enterprises.
- Minecraft: Helps game clients locate multiplayer servers.
- Kerberos: Used in secure authentication processes.
Troubleshooting SRV Records
If your SRV records aren’t working properly, check the following:
- Each target hostname must have a valid A or AAAA record.
- Ensure firewall ports match the SRV port numbers.
- Review priority and weight settings to prevent misrouting.
- Use our DNS Lookup Tool to verify DNS resolution.

Frequently Asked Questions About Service Lookup
1. What does an SRV record do?
An SRV record defines which server handles a specific service for your domain, specifying the port and protocol for that service.
2. How can I find SRV records for my domain?
Use HasheTools’ SRV Lookup Tool. Simply enter your domain and service type to see all associated SRV entries instantly.
3. What’s the difference between an SRV record and a CNAME record?
A CNAME record maps one domain name to another, while an SRV record defines how to reach a service (including port and protocol).
4. Can I have multiple SRV records for the same service?
Yes. Multiple SRV records can exist with different priorities and weights for load balancing or redundancy.
5. Do SRV records affect email delivery?
Typically, no, SRV records are used for services like SIP, LDAP, and XMPP. Email routing relies on MX records instead.
