# Lab 4.2: Small Enterprise-Class Lab

### Summary

During this lab we built on DHCP and VLAN confirmation as well added a bit of DNS knowledge. Very fun lab all around.

### Assigning IP helper addresses

1. Enter the `CLI` for a MLS
2. In `(config)` mode type `interface vlan {VLAN-ID}`
3. Then type `ip helper-address {IPaddr-DHCP-Server}`
4. Type `exit`
5. Repeat steps 2 to 4 for the rest of the VLANs

### DNS Setup

1. Click `Serivces` Tab
2. Select `DNS`
3. `Name` is the DNS record you want to set.&#x20;
4. Then set `Type` [Resources for DNS Types and Queries](https://ns1.com/resources/dns-types-records-servers-and-queries)
