DHCP Best Pratices? Might be a dumb question, but here it goes. Should DHCP be handled by the WSM server(win2003) or by my firewall? Is it better to have Z00D clients configured statically? Is there a best practice for DHCP configuration?
DHCP now supports option 82 (sub-option 5). You can use this option to allow DHCP proxy clients and relay agents to request an IP address for a specific subnet. If you are using a DHCP relay agent that is configured with DHCP option 82, sub-option 5, the relay agent can request an IP address lease for DHCP clients from a specific IP address range.

It is important to tag best practices for security while using the DHCP servers on your organizations network. Since DHCP is a protocol that do not need an authentication from the client, any user within or outside the network can obtain a lease of IP. This can reveal the data like DNS server IP or server data to the Aug 20, 2009 · For example: The 7 and 7 day intervals work hand in hand with a default DHCP lease time of 8 days. DHCP renewals are half the lease interval right, whcih is 4 days. If it doesn’t get renewed, then it waits until 87.5% of the lease time to renew, which is at the 7th day.
The proper Lease Time is whatever is appropriate for the use of the network it is implemented on. The most common Lease Time is 24 hours, as this is what many routers default to.
DNS and DHCP failures can also produce intermittent or delayed effects. Applications can run for hours or days, only to fail when an IP lease or a DNS address "time to live" expires, resulting in
Mar 30, 2009 · It can hurt performance if we use very less DHCP lease period (Less then 8 hours) or we have application which access domain controllers for GC info/LDAP requests/authentication, etc I believe with couple of hundred clients, performance will be not a big challenge for you (assume DC is running on good hardware config).
Like a lease on a car or apartment, a DHCP IP address lease has a fixed duration, and before it expires the lease must be renewed. On a typical home or small office router a DHCP lease may last between eight and 24 hours. Each time the lease is renewed (which happens automatically), there's a chance the device will receive a different IP address. DNS and DHCP failures can also produce intermittent or delayed effects. Applications can run for hours or days, only to fail when an IP lease or a DNS address "time to live" expires, resulting in Keep these intervals equal to or less than your DHCP lease period. If your DHCP lease is set to 8 days then 7 days for scavenging works great. That completes setting up aging for the zone. DHCP now supports option 82 (sub-option 5).
