Server with many IPs
Would it cause any possible network problems if I add 10 virtual NICs to one of our VM servers, and have each of them get it's own DHCP address? Each NIC would be on a different VLAN so the DHCP server will be assigning IPs based only on that VLAN.
Here's the reason:
We are experimenting with a Cloud-based anti-virus solution which requires a relay server to communicate with the cloud. The relay server, uses Windows network discovery to tell the Cloud all the machines visible to it using its network discovery method. Unfortunately, our environment is setup such that each department is on its own subnet, and the way network discovery works, is it's only able to see machines on its own broadcast domain. So it can't traverse VLANs. So my idea was to add a virtual NIC to this VM (relay server), and have each NIC be on a separate subnet. That way the relay server VM is able to have an IP address for each of the subnets, and thus network discovery will see ALL machines on all subnets, and report this to the cloud.
Does anyone see any possible network issues with a server with this setup?
What if I try to ping this server by its DNS name, which IP would it use?

It will work fine as long as you don't register each IP in DNS, as Steve mentioned.
