IP Address Management
Local DNS host address table
3-18 Preliminary January 30, 1998 Pipeline User’s Guide
You can check the list of host names and IP addresses in the table using the
termserv command Show Dnstab.
Configuring the local DNS table
To enable and configure the local DNS table:
1
Open the Ethernet > Mod Config > DNS menu.
2
Select List Attempt=Yes to allow a list of the IP addresses to be displayed
when using the terminal server command Dnstab Entry.
3
Select List Size and enter the number of entries you want in the list.
The minimum value is 1. The maximum value is 35.
The number of IP addresses displayed with the Dnstab Entry command
depends upon the value you set in the List Size parameter.
If List Attempt=Yes, and the name server returns an IP address list, the list is
copied into the entry in the local DNS table that matches the host name, up
to the number of entries you specify in List Size. When a list of IP addresses
for an entry is automatically updated, any existing list for that entry is
discarded.
For example:
– If you set List Size=4 and the remote DNS returns 3 entries, the entire
list of IP addresses in the local DNS table is cleared and the three
returned addresses are entered for the entry.
– If the local DNS table already contains 35 IP addresses for an entry and
the remote DNS server returns only 4, or if you set List Size=4, the first
four IP addresses are entered into the table for the entry and the
remaining addresses in the list are set to zero.
– If you set List Size=1, the list can contain only one IP address; any
others returned by the remote DNS are ignored. If you change the List
Size parameter value from a number greater than one to one, only the
first IP address is retained; all others are set to zero the next time the
table entry for that name is updated.

Select Enable Local DNS Table=Yes.
The default is No.
5
Select Loc DNS Tab Auto Update=Yes to enable automatic updating.
