    I've recently started working as a Network Analyst for a new company and their existing infrastructure is really something for the books... I have a 10.3.x.x /16 network with well over 512 hosts and no VLANs (one giant broadcast domain)

    I have to work with the 10.3.x.x subnet because Internal addresses are controlled by a third party, and I would really like to VLAN off this network, however I can't subnet the 10.3.x.x network because of the /16 mask and I can't get another internal subnet to migrate to, is their anyway I can VLAN/subnet off this existing 10.3.x.x /16 without re-doing the whole network at once and taking everything down?

    I've been going threw my CCNP/CCDA books but I can't seem find any other way out of this....

    Thoughts or do I have to bite the bullet on this?
