You might try the "iprange" packet matching module (-m iprange); it's not
domcumented in the man page, but "iptables -m iprange --help" prints the
following (at the end):
iprange match v1.2.9 options:
[!] --src-range ip-ip Match source IP in the specified range
[!] --dst-range ip-ip Match destination IP in the specified range
So you should be able to use something like:
iptables -A INPUT -m iprange --src-range 22.214.171.124-126.96.36.199 -j ACCEPT
This is present in SuSE 9.1, but apparently not in earlier versions.
