Finding a Host's MAC Address
- John McKeever
Customers who are using MettleCI as part of an IBM entitlement do not need to supply their MAC address so can safely ignore this page.
Customer’s licensing MettleCI directly from Data Migrators may be issued with a license tied to the MAC address of your development environment’s DataStage Engine which you’ll need to provide when ordering your MettleCI software.
A MAC (media access control) address is a unique identifier assigned to a network interface controller in a host machine. It is normally formatted as 6 double-character hexadecimal numbers with colon or hyphen delimiters (XX:XX:XX:XX:XX:XX or XX-XX-XX-XX-XX-XX).
Windows Hosts
You Windows host’s MAC address is described as the Physical Address of your Ethernet adapter when using the Windows ipconfig /all command:
C:\Users\John>ipconfig /all

Unix Hosts
As the root user (or user with appropriate permissions) you can use the command ifconfig -a on Linux to determine your MAC address. From the displayed information, find eth0 (this is the default first Ethernet adapter). The number may appear next to a test label HWaddr.
$> sudo ifconfig -a
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
options=1203<RXCSUM,TXCSUM,TXSTATUS,SW_TIMESTAMP>
inet 127.0.0.1 netmask 0xff000000
inet6 ::1 prefixlen 128
inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1
nd6 options=201<PERFORMNUD,DAD>
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
bridge0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
options=63<RXCSUM,TXCSUM,TSO4,TSO6>
ether 82:dc:5a:23:b0:00 <--------- YOUR MAC ADDRESS
Configuration:
id 0:0:0:0:0:0 priority 0 hellotime 0 fwddelay 0
maxage 0 holdcnt 0 proto stp maxaddr 100 timeout 1200

ipfilter disabled flags 0x0

ifmaxaddr 0 port 12 priority 0 path cost 0
AIX Hosts
On AIX environments, use the lscfg command:
# lscfg -vl ent0
ent0 U7H5F.001.FCD8675-P1-T9 2-Port 10/100/1000 Base-TX PCI-X Adapter (14532868)
2-Port 10/100/1000 Base-TX PCI-X Adapter:
Network Address.............000E418C0D3A <--------- YOUR MAC ADDRESS
ROM Level.(alterable).......XX0000
Hardware Location Code......U7H5F.001.FCD8675-P1-T9
PLATFORM SPECIFIC000E418C0D3A
Name: ethernet
Node: ethernet@1
Device Type: network
Physical Location: U7H5F.001.FCD8675-P1-T9
Or you may see results similar to this
Your MAC address is the “Network Address” and you will have to put the colons in yourself when using it to request your license (000E418C0D3A becomes 00:0E:41:8C:0D:3A in this example)
