Hi Orange,

L was introduced (together with M) with SOA# 1997031300

.                         518400     NS    L.ROOT-SERVERS.NET.
L.ROOT-SERVERS.NET.       518400     A     192.0.5.12

The address was first changed between 1998020200 and 1998020400

-L.ROOT-SERVERS.NET.       518400     A     192.0.5.12
+L.ROOT-SERVERS.NET.       518400     A     198.32.64.12

Then again between 2007103101 and 2007110100

-L.ROOT-SERVERS.NET. A 198.32.64.12
+L.ROOT-SERVERS.NET. A 199.7.83.42
