Untuk memberikan IP alias pada sebuah Ethernet card (dalam contoh digunakan interface rl0), perhatikan contoh berikut :<\/p>\n

[nanang@oprex] # ifconfig rl0
\nrl0: flags=8843 mtu 1500
\ninet 192.168.10.1 netmask 0xfffffff0 broadcast 192.168.10.15
\ninet6 fe80::210:a7ff:fe01:f49a%rl0 prefixlen 64 scopeid 0\u00d71
\nether 00:10:a7:01:f4:9a
\nmedia: Ethernet autoselect (100baseTX )
\nstatus: active<\/p>\n

Dapat dilihat bahwa Ethernet tersebut (rl0) memiliki IP 192.168.10.1, kita akan coba memberikan IP lain (192.168.10.10) pada rl0 :<\/p>\n

[nanang@oprex] # ifconfig rl0 inet 192.168.10.10 netmask 255.255.255.0 alias<\/p>\n

##Kemudian Coba Kita Lihat##<\/p>\n

[nanang@oprex] # ifconfig rl0
\nrl0: flags=8843 mtu 1500
\ninet 192.168.10.1 netmask 0xfffffff0 broadcast 192.168.10.15
\ninet6 fe80::210:a7ff:fe01:f49a%rl0 prefixlen 64 scopeid 0\u00d71
\ninet 192.168.10.10 netmask 0xfffffff0 broadcast 192.168.10.255
\nether 00:10:a7:01:f4:9a
\nmedia: Ethernet autoselect (100baseTX )
\nstatus: active<\/p>\n

Sekarang rl0 telah memiliki dua IP address, yaitu : 192.168.10.1 dan 192.168.10.10, kita cek dengan menggunakan ping :<\/p>\n

[nanang@oprex] # ping 192.168.10.10
\nPING 192.168.10.10 (192.168.10.10): 56 data bytes
\n64 bytes from 192.168.10.10: icmp_seq=0 ttl=64 time=0.196 ms
\n64 bytes from 192.168.10.10: icmp_seq=1 ttl=64 time=0.137 ms
\n64 bytes from 192.168.10.10: icmp_seq=2 ttl=64 time=0.135 ms
\n64 bytes from 192.168.10.10: icmp_seq=3 ttl=64 time=0.137 ms
\n^C

\n4 packets transmitted, 4 packets received, 0% packet loss
\nround-trip min\/avg\/max\/stddev = 0.135\/0.151\/0.196\/0.026 ms<\/p>\n

Untuk menambahkan IP alias setiap kali system start, Edit rc.conf dan tambahkan :
\n[nanang@oprex] # ee \/etc\/rc.conf<\/p>\n

hostname=\u201dnanang.gagah.com\u201d
\nnetwork_interfaces=\u201dauto\u201d
\nifconfig_rl0=\u201dinet 192.168.10.1 netmask 255.255.255.0\u2033
\nifconfig_rl0_alias0=\u201dinet 192.168.10.10 netmask 255.255.255.0\u2033
\nifconfig_lo0=\u201dinet 127.0.0.1\u2033
\ngateway_enable=\u201dYES\u201d<\/p>\n

kern_securelevel_enable=\u201dNO\u201d
\nnfs_reserved_port_only=\u201dYES\u201d
\npccard_enable=\u201dYES\u201d
\npccard_mem=\u201dDEFAULT\u201d
\npccard_flags=\u201d-i 5\u2033
\nsendmail_enable=\u201dNO\u201d
\nsshd_enable=\u201dYES\u201d
\nusbd_enable=\u201dYES\u201d<\/p>\n

contoh diatas adalah apabila kita akan menambahkan IP alias pada rl0 dengan satu IP ( 192.168.10.10) bila ingin menambahkan IP yang lain juga bisa, dengan catatan dimulai dengan ifconfig_rl0_alias0=\u201d” dan seterusnya.<\/p>\n

Untuk menghilangkan IP alias dapat dilakukan dengan :<\/p>\n

[nanang@oprex] # ifconfig rl0 inet 192.168.10.10 -alias
\n[nanang@oprex] # ifconfig rl0
\nrl0: flags=8843 mtu 1500
\ninet 192.168.10.1 netmask 0xfffffff0 broadcast 192.168.10.15
\ninet6 fe80::210:a7ff:fe01:f49a%rl0 prefixlen 64 scopeid 0\u00d71
\nether 00:10:a7:01:f4:9a
\nmedia: Ethernet autoselect (100baseTX )
\nstatus: active<\/p>\n

Selamat Mencoba, Semoga Berhasil<\/p>\n
