Dynamic DNS

The Domain Name System (DNS) is the Internet protocol for mapping a hostname to its IP address. DNS allows users to enter more readily memorable and intuitive hostnames, rather than IP addresses, to identify devices connected to a network.

Hostname resolution can be either static or dynamic.
  • In static resolution, a local table is defined on the interconnect that associates hostnames with their IP addresses. Static tables can be used to speed up the resolution of frequently queried hosts.

  • Dynamic resolution requires that the interconnect query a DNS server located elsewhere on the network. Dynamic name resolution takes more time than static name resolution, but requires far less configuration and management.

Dynamic DNS update configuration support enables HPE Virtual Connect SE 100Gb F32 Module for HPE Synergy interconnects to update the DNS server when the IP address or hostname is changed. This functionality is applicable for both IPv4 as well as IPv6 addresses. You can enable or disable the Dynamic DNS feature.
