unterstützen die DNS Server von Kabel Deutschland eigentlich EDNS0 (RFC 2671)? http://tools.ietf.org/html/rfc2671
Ich hab mal versucht das anhand einem einfachen nslookup raus zu finden, und denke das klappt nicht:
Code: Alles auswählen
H:\>nslookup -type=TXT rs.dns-oarc.net 83.169.184.161
Server: 83-169-184-161-isp.superkabel.de
Address: 83.169.184.161
Non-authoritative answer:
rs.dns-oarc.net canonical name = rst.x476.rs.dns-oarc.net
rst.x476.rs.dns-oarc.net canonical name = rst.x485.x476.rs.dns-oarc.net
rst.x485.x476.rs.dns-oarc.net canonical name = rst.x490.x485.x476.rs.dns-oarc.
net
rst.x490.x485.x476.rs.dns-oarc.net text =
"83.169.184.161 DNS reply size limit is at least 490"
rst.x490.x485.x476.rs.dns-oarc.net text =
"83.169.184.161 lacks EDNS, defaults to 512"
rst.x490.x485.x476.rs.dns-oarc.net text =
"Tested at 2012-03-31 10:05:15 UTC"
Code: Alles auswählen
