(config)>

Configure access control:
- To limit access to specified IPv4 addresses and networks:
```
(config)> add service mdns acl address end value
(config)>
```
  Where value can be:
  - A single IP address or host name.
  - A network designation in CIDR notation, for example, 192.168.1.0/24.
  - any: No limit to IPv4 addresses that can access the mDNS service.
  Repeat this step to list additional IP addresses or networks.
- To limit access to specified IPv6 addresses and networks:
```
(config)> add service mdns acl address6 end value
(config)>
```
  Where value can be:
  - A single IP address or host name.
  - A network designation in CIDR notation, for example, 2001:db8::/48.
  - any: No limit to IPv6 addresses that can access the mDNS service.
  Repeat this step to list additional IP addresses or networks.
- To limit access to hosts connected through a specified interface on the 6310-DX device:
```
(config)> add service mdns acl interface end value
(config)>
```
  Where value is an interface defined on your device.
