This may be a feature of your cable company, since I have a hostname
defined in /etc/myname and get an IP from my cable company with no
However, I'm not sure why you feel you need to override the
cable-supplied hostname. For me:
rs ~$ hostname
rs ~$ cat /etc/myname
I find this useful in some contexts wherein I don't wish to reveal who
I "really" am, and I can use it for local LAN purposes. However:
rs ~$ ifconfig ex0
ex0: flags=8863<UP,BROADCAST,NOTRAILERS,RUNNING,SIMPLEX,MULTICAST> mtu
media: Ethernet autoselect (10baseT)
inet 220.127.116.118 netmask 0xfffffc00
rs ~$ host 18.104.22.1688
622.214.171.124.IN-ADDR.ARPA domain name pointer ip12-3-45-678.ri.ri.cox.net
(IP munged, of course...)
So, I have a "real" internet IP address, and a "real" internet
hostname, in the sense that one can look up the one with the other
with a "real" DNS service.
Are you saying you want the "real" IP address, but wish to assign your
own made-up hostname to it? What does this gain you? Sometimes I wish
to override dhcp host-provided data, particularly DNS server IPs, and
then I use a 'prepend' statement in a /etc/dhclient.conf file. But
currently, I don't even have one of those files! Don't need it.
(And, I realize we're rapidly lurching off-topic...)
