You can check the IP Services table for a list of IP addresses that are associated
with a protocol.

## Before you begin

Role required: admin

## About this task

The IP Services table maps a port to a protocol. Several mappings are provided by default for commonly used port-protocol combinations, such as port 80 for HTTP, port 22 for SSH, and port 161 for SNMP.

A system property
called glide.discovery.ip_service_affinity allows Discovery to remember the last port of the IP address that was discovered.  
Important:  
You should not modify IP services unless your organization uses custom ports.

## Procedure

1. Navigate to AllDiscovery DefinitionIP Services.
2. Filter the list to find the appropriate IP service.
3. Click the name of the service to go to that IP service page.
4. Click the IP Service Affinities tab for the list of IP addresses associated with that service.
