Thanks, Matt. I cannot ping it either on that machine or on any other machine I have access to. Is the netmask setting I mentioned in my previous email OK? Does anything else need to be changed or is the /etc/rc.conf file the only place where IP address info is stored and configured? Also is it OK for me to have a different range of IP addresses on the same machine? For example, here is what I have in /etc/rc.conf now: #New addresses: ifconfig_xl0_alias0="inet 208.184.116.19 netmask 255.255.255.192" ifconfig_xl0_alias1="inet 208.184.116.48 netmask 255.255.255.192" ifconfig_xl0_alias2="inet 208.184.116.21 netmask 255.255.255.192" ifconfig_xl0_alias3="inet 208.184.116.22 netmask 255.255.255.192" ifconfig_xl0_alias4="inet 208.184.116.23 netmask 255.255.255.192" ifconfig_xl0_alias5="inet 208.184.116.24 netmask 255.255.255.192" ifconfig_xl0_alias6="inet 208.184.116.25 netmask 255.255.255.192" ifconfig_xl0_alias7="inet 208.184.116.26 netmask 255.255.255.192" ifconfig_xl0_alias8="inet 208.184.116.27 netmask 255.255.255.192" ifconfig_xl0_alias9="inet 208.184.116.28 netmask 255.255.255.192" ifconfig_xl0_alias10="inet 208.184.116.29 netmask 255.255.255.192" ifconfig_xl0_alias11="inet 208.184.116.30 netmask 255.255.255.192" ifconfig_xl0_alias12="inet 208.184.116.31 netmask 255.255.255.192" ifconfig_xl0_alias13="inet 208.184.116.32 netmask 255.255.255.192" ifconfig_xl0_alias14="inet 208.184.116.33 netmask 255.255.255.192" ifconfig_xl0_alias15="inet 208.184.116.44 netmask 255.255.255.192" ifconfig_xl0_alias16="inet 208.184.116.45 netmask 255.255.255.192" ifconfig_xl0_alias17="inet 208.184.116.46 netmask 255.255.255.192" ifconfig_xl0_alias18="inet 208.184.116.20 netmask 255.255.255.192" ifconfig_xl0_alias19="inet 208.184.116.49 netmask 255.255.255.192" ifconfig_xl0_alias20="inet 208.184.116.50 netmask 255.255.255.192" ifconfig_x10_alias21="inet 207.126.103.75 netmask 255.255.255.192" The entry I added (and that is not responding to pings) is the last entry.
