Wildcard records allow an administrator to point all non-existent records within a domain to a single target host (not including names defined implicitly through records created in a lower name space). It is important to note that a wild card record is not inclusive of the root record of the domain.
A wild card record can be defined as an A Record, AAAA Record, CNAME Record, and HTTP Redirection Record by putting an * in the name field.
1. Select your Domain
A. Select Managed DNS
B. Select Domains from the dropdown
C. Select the domain you want to add a wildcard record too. In this example we will use A records.
2. Select Record Type
Under the A records section, click the (+) icon to add a record.
3. Enter Record Values
A. Name: The hostname for the record. For a wildcard you would enter * or *.subdomain to catch all queries for *.domain.com or *.subdomain.domain.com.
B. TTL: Time to Live, measured in seconds, determines how long the record is cached in resolvers. For more information on best practices for TTLs, click here.
C. Record Mode: The Record Mode is how you enable settings like Failover, Record Pools, or Round Robin with Failover. You can read more about these settings here.
D. Geo Proximity: You can select a Geo Proximity rule to apply to the record, for more information on Geo Proximity, click here.
E. IP Filter: You can select an IP Filter to apply to the record, for more information on IP Filters, click here.
F. Disable Record: Information on the NX Domain feature can be found in the Disabling a Record tutorial.
G. IP: The IPv4 address to send all queries to. If you don't want traffic to come to your servers for this record, we recommend using the loopback IP, 127.0.0.1.
H. Notes: Add a helpful note with keywords so you can search for your records later.
I. Save and Close/Continue: Save and Close to finish entering A records or Save and Continue to add more records of the same type.
