IP Changed to Directional Pool Not Resolving

Before making any changes to any Directional DNS records, lower the TTL value. 

This ensures that changes are propagated quickly on recursive nameservers. 

The TTL values in the recursive servers need to expire before they can cache the new information. 

To monitor the TTL value at any time, run a dig against each recursive nameserver.

1. Check general digs to determine accuracy of local resolution of hostname

   1. Go to online dig tool at https://digwebinterface.com
   2. Enter <hostname> in Hostnames or IP addresses
   3. Under Type leave Unspecified
   4. Under Options select Show Command and Trace
   5. Under Nameservers leave Default
   6. Press Dig
   7. Check dig result
      1. Ensure Answer section is returned
      2. Ensure Authoritative section shows UltraDNS nameservers
      3. Ensure Answer section shows correct information i.e, correct IP/hostname based on Directional/Geo IP configuration

2. Check digs against UltraDNS nameservers to determine correct resolution of hostname

   1. Go to online dig tool at https://digwebinterface.com/
   2. Enter <hostname> in Hostnames or IP addresses
   3. Under Type leave Unspecified
   4. Under Options select Show Command and Trace
   5. Under Nameservers select Specify Myself and enter Vercara nameservers
   6. Click on Dig
   7. Check dig result
      1. Ensure Answer section is returned
      2. Ensure Authoritative section shows UltraDNS nameservers
      3. Ensure Answer section shows correct information i.e, correct IP/hostname based on Directional/Geo IP configuration

3. Check digs against recursive nameservers to determine correct resolution of hostname

   1. Go to online dig tool at https://digwebinterface.com/
   2. Enter <hostname> in Hostnames or IP addresses
   3. Select ANY under Type
   4. Select ALL under Nameservers
   5. Do not select any check boxes under Options
   6. Click on Dig
   7. Check dig result
      1. If recursive nameservers are not answering correctly by recursive server location, check TTL value
      2. If the TTL value is high, the TTL value will need to expire on the recursive server before it can cache the new information
