php search on a partial IP address stored in mysql as unsigned int -



php search on a partial IP address stored in mysql as unsigned int -

i have mysql db includes ip addresses. on search form, client wants search on partial ip address , have (perhaps) many results pop up. storing ip addresses in mysql unsigned int. using php 5.2, not have access php 5.7 , inet6_ntoa function.

the current db has on 50,000 records , continues grow, don't want have convert ip's dotted notation, match - seems bit unwieldy.

is there improve way me search on partial ip address? client insistent on this, there no choice.

ps. i'm displaying info in datatables-1.10 shouldn't have way searching - fyi.

assuming dealing ipv4 addresses, each address nil 32 bits.

there mysql inet_ntoa function responsible homecoming string ip.

so, might want utilize smth like:

select ... ... inet_ntoa(...) (...)

hope helps.

upd: increment productivity suggest update table adding new char(16) field string representation of ip , trigger on update fill field inet_ntoa(...) value. selecting against field work charm.
