Parameters
host-name: Specifies a host name, a case-insensitive string of 1 to 253 characters. It can include letters,
digits, hyphens (-), underscores (_), and dots (.).
ip-address: Specifies the IPv4 address of the host.
vpn-instance vpn-instance-name: Specifies the name of an MPLS L3VPN instance, a case-sensitive string
of 1 to 31 characters. To specify a host name-to-IP address mapping on the public network, do not
specify this option.
Usage guidelines
You can configure host name-to-IPv4 address mappings for the public network and up to 1024 VPNs,
and configure a maximum of 1024 host name-to-IPv4 address mappings for the public network or each
VPN.
On the public network or a VPN, each host name maps to only one IPv4 address. If you use the
command multiple times, the most recent configuration takes effect.
Examples
# Map the IPv4 address 10.110.0.1 to the host name aaa on the public network.
<Sysname> system-view
[Sysname] ip host aaa 10.110.0.1
