• Configure your pri-dns server to implement and provide the DNSSEC records for your assignment domain.
  • Provide the administrator for your top domain (The root name server operator(s)) with a copy of the DS key for your domain. If you have not already done so, include the glue record as well.
  • Configure a DNSSEC Trust Anchor so that your co-nfs server considers your primary DNS server (the one with the <yourname>.ops zone) to already be authenticated.

Supporting Services

You need the following services and network infrastructure to support your Internet Email System (some of which should have been configured in assignment 1):

• pri-dns must be the primary DNS name server for your domain with the proper MX record(s), SPF record(s), A record(s), and PTR record(s). It must be queriable by any machines in the 192.168.0.0/16 network.
  • Provide the root name server operator(s) of the <yourname>.ops domain with glue records for your domain.
• co-nfs must be a caching DNS server, accessible only to machines in your networks, that will start its query with the root name server(s) in the virtual lab (e.g. rns-ldap.rdu6.ops (192.168.6.4), rns-ldap.wsu15.ops (192.168.35.4)), and then the appropriate primary DNS server.
• if you are one of the root name server operators, your rns-ldap must provide authoritative responses to any valid DNS queries.
  • All authorized root name servers in the virtual lab must be queriable by any network devices from the 192.168.0.0/16 network.
