I have a Windows 7 PC (Name: Bbloomfield) on the network that receives IP address from the DHCP server from the Domain Controller. The IP address is and  computer name is "BBloomfield.nxxxco.com".

When I ping the computer name from this computer, it displays IPv6 address as shown below instead of . However when I ping the computer name from another computer on the same network, it returns

DNS server shows as seen above.

Is this because IPv6 is enabled on TCP/IP property window? We do not use IPv6 at all. There are less than 15 PCs in the office. Should I disable IPv6 on each computer TCP/IP properties? Is there a downside for disabling IPv6?

You can disable ipV6 on client systems , if your enviornment is not using ipV6.

The reason you are seeing IPV6 IP address is you have the IPV6 enabled on the NIC as you have stated , also I Belive , the registry entry for DHCP for IPv6 has not  been disabled.

So , I would suggest uncheck the ipV6 from NIC property and disable it from registry as well,

Read my article where to disable  it in Registry

Hope this helps.

It will do no harm to leave IP6 enabled, even though you do not use IP6 as such some windows functions increasingly use IP6

What is obvious problem/disadvantage with disabling IPv6?
Based on articles given above, IPv6 does not seem to apply on a 15 computer network.

on a windows network, it is said that some features require ipv6. microsoft's docs state in various places that ipv6 is mandatory for proper domain operation though none of the ones i browsed ever listed the features that would fail without it. any other system will not care if it uses ipv6 or ipv4.

i can tell you that a regular dc setup with file shares, possibly roaming profiles, and GPOs works fine without ipv6.

ipv6 does apply on a 15 computers network but is uselessly complex, likely insecure, messy by design...

You can ping with the "-4" option to get ipV4 addresses.
