IPv4 address allocation policy is defined in RFC-2050 and the specific
registry policies of the ISP's home registry. For you that is currently
RIPE-NCC (http://www.ripe.net). On thing to remember is that you do not
"own" IPv4 addresses. You are allocated IPv4 addresses. Check with the
documentation at RIPE-NCC for details.
Doing a quick check on the IP address we get the following at RIPE-NCC:
[Query: 18.104.22.168, Server: whois.ripe.net]

This is _not_ a contiguous block. 188.8.131.52/24 and 184.108.40.206/24 are
both allocated to others (one in France, the other in Zimbabwe.
Hence, given your current allocation of 220.127.116.11/24, you can get a
second link to the Internet and advertise out that link with this /24 block.
Personally, I would recommend that any new IPv4 addresses you need come from
a larger contiguous block of addresses. That way you would advertise /23,
then a /22, then a /21, etc - keeping your advertisement to the Internet
down to just one prefix (i.e. one network statement). This is your part to
keeping the Internet routing table from growing too fast.
