Figure 13. Work with Host Table Entries, Display 2 of 2

The iSeries TCP/IP host table is shipped with the LOOPBACK entry. The LOOPBACK entry has an Internet address of 127.0.0.1 and two host names: LOOPBACK and LOCALHOST.

The 127.0.0.1 Internet address can be changed (CHGTCPHTE) and a different one can be added (ADDTCPHTE). The local table command processing programs ensure that any LOOPBACK host name added or changed in the host table is in the range of 127.0.0.1 to 127.255.255.254. Multiple loopback host table entries are allowed in the server host table.

You may alter the LOOPBACK host name or add additional host names using the (CHGTCPHTE) command.

If the LOOPBACK or LOCALHOST name is changed or removed from the host table, the name is not valid, unless the domain name server has a LOOPBACK entry that specifies this value as a host name.

You can define up to four names for each Internet address. If the TCP/IP host is in your local domain, then it is not necessary to qualify the host with the domain name. As long as a TCP/IP host is in your local domain, you need only to enter the host name with the host table entry.

However, if you would like to add TCP/IP hosts that are outside of your local domain, you need to add these TCP/IP hosts as fully qualified. The fully qualified host name of SYSNAMEND.ENDICOTT.IBM.COM shows this as an example in Figure 14 on page 21.
