+= Requirements for installation in an IPv4 network
+
+The following requirements apply to installations in an IPv4 network:
+
+* An IPv6 loopback must be configured on the base system.
+The loopback is typically configured by default.
+Do not disable it.
+* Do not disable IPv6 in kernel by adding the `ipv6.disable=1` kernel parameter.

+For a supported way to disable the IPv6 protocol, see link:https://access.redhat.com/solutions/5045841[How do I disable the IPv6 protocol on Red Hat Satellite and/or Red Hat Capsule server?] in Red{nbsp}Hat Knowledgebase.
