[dns-operations] Question about L-Root IP address

[Yasuhiro Orange Morishita / 森下泰宏]

Peter-san:

I remember the official debut date of M-Root is Aug 22, 1997.
In the root hint file:
<http://cvsweb.netbsd.org/bsdweb.cgi/src/etc/namedb/root.cache.diff?r1=1.7&r2=1.8>

Kato-san's thesis described the same date. (caution: it's written in Japanese)
<http://www.nic.ad.jp/ja/materials/iw/1997/proceedings/IPM-PDF/kato.pdf>

And now, I'm a little bit confused.
Is your SOA# is "root-servers.net"'s maybe?
