Either use ipset (needs a patched kernel), or iprange (if the addresses
are consecutive) or use a subchain, e.g:

-A -s 10.10.10.1 -j CUSTOM
-A -s 10.10.10.2 -j CUSTOM
-N CUSTOM
-A CUSTOM <rest of rule>

Thank you!
Subchains seem to be OK for my needs. But will
subchains work in case when I need to *exclude* some
IPs?

For example, can I add 10.10.10.2 to this rule using
subchain?

iptables -I INPUT -p tcp --dport 80 ! -s 10.10.10.1
-m state --state NEW -m recent --set

Yes.

-I INPUT -p tcp --dport 80 -j CUSTOM
-A CUSTOM -s 10.10.10.1 -j RETURN
-A CUSTOM -s 10.10.10.2 -j RETURN
-A CUSTOM -m state --state NEW -m recent --set
