Domain Name Server Files
DNSHOSTS
The DNSHOSTS file specifies the name-to-address mapping along with other
information on the hosts. This file is not the same as the hosts file
($SYSTEM.ZTCPIP.HOSTS).
An example of the DNSHOSTS file is as follows:
@ IN SOA jiffy.kentcomm.com.
joe.jiffy.kentcomm.com. (
1.1 ; Serial
3600 ; Refresh
300 ; Retry
3600000 ; Expire
3600 ) ; Minimum
IN NS pubs.kentcomm.com.
IN NS jiffy.kentcomm.com.
local host IN A 127.1
jiffy IN A 128.33.4
IN A 10.0.0.78
ANY HINFO SUN-SPARCSTATION-20 UNIX
lightning IN CNAME jiffy

ANY HINFO SUN-SPARCSTATION-20 UNIX

ANY HINFO TANDEM/K2000 GUARDIAN

fred IN MX 0 jiffy.kentcomm.com

postmaster ANY MR joe
Bind ANY MINFO Bind-Request kjd.BigCityU.Edu.
ANY MG Ralph.BigCityU.Edu.
ANY MG Zhou.BigCityU.Edu.
ANY MG Painter.BigCityU.Edu.
ANY MG Riggle.BigCityU.Edu.
ANY MG Terry.pa.XYZCorp.Com.
In the example, the MG and MINFO lines do not have much meaning in the NonStop
environment, because they are typically integrated with mail systems. On NonStop
machines the mail system is maintained by TRANSFER, which cannot have the
domain name server integrated with it. Do not include any MG or MINFO records for
NonStop hosts.
