Assigning an EIP and Binding It to an ECS¶
Scenarios¶
You can assign an EIP and bind it to an ECS so that the ECS can access the Internet.
Assigning an EIP¶
Log in to the management console.
Click
in the upper left corner and select the desired region and project.On the console homepage, under Network, click Elastic IP.
On the displayed page, click Assign EIP.
Set the parameters as prompted.
Table 1 Parameter descriptions¶ Parameter
Description
Example Value
Region
Regions are geographic areas that are physically isolated from each other. The networks inside different regions are not connected to each other, so resources cannot be shared across different regions. For lower network latency and faster access to your resources, select the region nearest you.
ec-ch2
EIP Type
Dynamic BGP: Dynamic BGP provides automatic failover and chooses the optimal path when a network connection fails.
Dynamic BGP
Billed By
The following bandwidth types are available:
Dedicated: The bandwidth can be used by only one EIP.
Shared: The bandwidth can be shared by multiple EIPs.
Dedicated
Bandwidth
The bandwidth size in Mbit/s.
100
Bandwidth Name
The name of the bandwidth.
bandwidth
Tag
The EIP tags. Each tag contains a key and value pair.
The tag key and value must meet the requirements listed in Table 2.
Key: Ipv4_key1
Value: 192.168.12.10
Quantity

Click Submit.
Binding an EIP¶
On the EIPs page, locate the row that contains the target EIP, and click Bind.
Select the instance to which you want to bind the EIP.
Click OK.
Follow-Up Procedure¶
After an ECS with an EIP bound is created, the system generates a domain name in the format of ecs-xx-xx-xx-xx.compute.xxx.com for the EIP by default. xx-xx-xx-xx indicates the EIP, and xxx indicates the domain name of the cloud service provider. You can use the domain name to access the ECS.
You can use any of the following commands to obtain the domain name of an EIP:
ping -a EIP
nslookup [-qt=ptr] EIP
dig -x EIP
