Separation of functions is a useful concept in any management regime. For many, it makes sense to let routers concentrate on constructing FIBs and routing packets (with some possible minor DHCP relay activities), let end system managers control end systems using business-appropriate tools, and generally get on with business using whatever tools are both useful and amenable to economical management. DHCP seems to be one of these tools. Deliberately blocking use of such tools seems foolhardy at best.</div><div><br class=""></div><div class=""><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; line-height: normal; border-spacing: 0px;"><span class="Apple-style-span" style="border-collapse: separate; font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; line-height: normal; border-spacing: 0px;"><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px; font-size: 12px; font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; line-height: normal;"><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px; font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; line-height: normal;"><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px; font-variant-ligatures: normal; font-variant-position: normal; font-variant-numeric: normal; font-variant-alternates: normal; font-variant-east-asian: normal; line-height: normal;"><div class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">James R.
