Add DNS Records to Your Subdomain

This guide shows how to add records under your subdomain, such as houston.ki5qkx.ampr.org.

To claim your callsign subdomain, see Claim Subdomain

1. Open Your Subdomain

1. Go to DNS → My subdomains.
2. Find your subdomain (for example ki5qkx.ampr.org).
3. Click the Resource Records action button.
4. Click the Add a resource record button.

2. Choose a Record Type

Common record types include:

• A and AAAA: IPv4/IPv6 address records
• CNAME: alias
• MX: mail exchange
• TXT: text data
• SRV: service records

The Portal also supports CAA, LOC, RP, PTR, NS, DNSKEY, and DS where applicable.

3. Enter Record Data

The record form fields will adjust according to the type of record you selected.

For example, if you chose 'A' record, these fields appear:

• Hostname:
  • Enter only the left-hand part of the name (not the whole fully qualified name).
  • Example: to create houston.ki5qkx.ampr.org, enter houston.
  • Enter @ to target the subdomain apex (ki5qkx.ampr.org).
• TTL:
  • Number of seconds resolvers will keep responses cached.
  • Leave blank for the default value (1 day).
• Data:
  • Enter the value for this record.
  • For instance, IP address, target name, text, etc.
• Active:
  • Leave checked unless you want to create the record without publishing it.

Example: Create an A Record

• We want houston.ki5qkx.ampr.org to point to 44.63.31.65.
• We have already claimed ki5qkx.ampr.org as a callsign-based subdomain.

When filling out the record form:

1. Choose type A.
2. Hostname: houston
3. IPv4 Address: 44.63.31.65
4. TTL: 300 (300 seconds = 5 minutes)
5. Click Create.

At the top of the next hour, the updated records should be pushed to the ampr.org name servers and you should begin to see the changes.
