Port 10116 NETIQ-VOIPA
Port 10116 is the IANA-assigned netiq-voipa port for NetIQ VoIP Assessor (TCP / UDP).
What is port 10116 used for?
Port 10116 is assigned to netiq-voipa and uses TCP / UDP. The IANA registry describes the service as “NetIQ VoIP Assessor”. It sits above the registered range, where most numbers are transient client ports. A fixed high port is worth documenting precisely because tooling often assumes the default.
Ports are the transport-layer address a service listens on. A client that wants to reach netiq-voipa connects to port 10116. A TCP connection is refused when nothing is listening, while a UDP request simply goes unanswered. That is why a port conflict appears whenever two processes try to bind the same number.
Use the commands below to confirm whether port 10116 is actually in use before you change firewall rules. Blocking the port stops new inbound traffic at the firewall, but it does not stop a local process from listening, and it does not remove the service from the machine.

Check and block port 10116
Copy-ready commands for the protocols assigned to this port. Run the check first, then block only what should not be reachable.
Check on Linux
sudo ss -tlpn 'sport = :10116'
sudo ss -ulpn 'sport = :10116'Check on Windows
Get-NetTCPConnection -LocalPort 10116 -State Listen -ErrorAction SilentlyContinue
Get-NetUDPEndpoint -LocalPort 10116 -ErrorAction SilentlyContinueBlock with UFW
sudo ufw deny 10116/tcp
sudo ufw deny 10116/udpBlock with iptables
sudo iptables -A INPUT -p tcp --dport 10116 -j DROP
sudo iptables -A INPUT -p udp --dport 10116 -j DROPThese commands are examples for a typical host. Check the listener before you change firewall rules, and persist iptables rules with iptables-save or netfilter-persistent. On Windows, use Windows Defender Firewall or New-NetFirewallRule for persistent blocks. The iptables rules here cover IPv4; mirror them with ip6tables if IPv6 is enabled.
Is port 10116 safe to expose?
This port is not on our curated list of services with a widely exploited profile. Exposure is only safe when the listening service is intended, patched and protected by a firewall. Keep the listening service patched and remove it if unused. A default-deny firewall policy with explicit allow rules is still the safest baseline.
Where port 10116 is usually used
Most traffic on port 10116 falls into these scenarios. The demo below is a safe way to confirm the listener before you change anything.
- VoIP call setup and media streams between clients and a PBX.
- Conference, contact-centre or SIP-trunk infrastructure.
- Firewall reviews for real-time traffic that is sensitive to latency.
Probe the signalling port
SIP and media traffic may use TCP or UDP depending on the provider, so confirm the transport before you test.
nc -vz 127.0.0.1 10116Common problems with port 10116
Connection refused or timed out
Refused usually means the host is reachable but nothing is listening on port 10116. A timeout more often means a firewall drop, a wrong host or a service bound to a different interface.
Port already in use
Find the process holding the port with sudo ss -tlpn 'sport = :10116' or sudo lsof -i :10116. Stop that process or configure it to bind another port; killing it without identifying it can take down a production service.
Firewall rule did not survive a reboot
UFW and Windows Firewall keep rules across restarts. Raw iptables rules do not: save them with iptables-save or the netfilter-persistent package, and re-apply after upgrades that reset the ruleset.
The port is blocked but still reachable
A firewall rule filters inbound traffic; it does not close the listener. Confirm with the check command above and bind the service to 127.0.0.1 when only local clients need it.

Frequently asked questions
What is port 10116 used for?
Port 10116 (NETIQ-VOIPA) uses TCP / UDP. NetIQ VoIP Assessor.
How do I check if port 10116 is open?
On Linux run `sudo ss -tlpn 'sport = :10116'` and `sudo ss -ulpn 'sport = :10116'`. On Windows run `Get-NetTCPConnection -LocalPort 10116 -State Listen -ErrorAction SilentlyContinue` and `Get-NetUDPEndpoint -LocalPort 10116 -ErrorAction SilentlyContinue` in PowerShell. If the port is open, the output shows a process listening on port 10116; empty output usually means nothing is bound to it.
How do I block port 10116?
With UFW run `sudo ufw deny 10116/tcp` and `sudo ufw deny 10116/udp`. With iptables run `sudo iptables -A INPUT -p tcp --dport 10116 -j DROP` and `sudo iptables -A INPUT -p udp --dport 10116 -j DROP`. Persist the iptables rules with your distribution's netfilter-persistent or iptables-save tooling so they survive a reboot.
Is port 10116 safe to expose?
This port is not on our curated list of services with a widely exploited profile. Exposure is only safe when the listening service is intended, patched and protected by a firewall. Nevertheless, keep the listening service patched and remove it if unused. A default-deny firewall policy with explicit allow rules is still the safest baseline.
