the address in 127.0.1.0/24 and 127.0.2.0/24 are needed for TestMemberlist_JoinDifferentNetworksMultiMasks and TestMemberlist_JoinDifferentNetworksUniqueMask. Only a few addresses are needed in these tests. Creating too many addresses in loopback may cause unexpected problems on network stack of local machine. For example, git can not resolve github.com on my laptop!
