Domain Name System (DNS)

DoD INF1 provides two DNS service offerings.

Second Level Domain (SLD)

SLD1 is a second level .mil domain host (ex. domain.mil). These name servers are registered in the nic.mil registry and available for both public and dod queries. These DNS hosts are intended to host domains up to 50 records. Domains with grater than 50 records should sub-delegate third and fourth level domains to the EDS service offering.

Name Servers: ns1.sld1.inf.dns.mil, ns2.sld1.inf.dns.mil, ns3.sld1.inf.dns.mil

Enterprise Domain Service (EDS1)

EDS1 is an enterprise DNS offering. These name servers are not registered with the nic.mil service and hence cannot host second level domains. Only third and fourth level domains can be delegated to these servers. There is no limit on host records with this service.

Name Servers: ns1.eds1.inf.dns.mil, ns2.eds1.inf.dns.mil, ns3.eds1.inf.dns.mil

Second Level Domain Commercial (SLD2)

SLD2 is a second level .com domain host (ex. domain.com). These DNS hosts are intended to host domains up to 50 records. Domains with grater than 50 records should sub-delegate third and fourth level domains to the EDS service offering.

Name Servers: ns1.sld2.inf.dns.mil, ns2.sld2.inf.dns.mil, ns3.sld2.inf.dns.mil
