protocol.addrs
Read, write, and manipulate address data.
Reader functions take [buf start ctx] and return [end value] where end is the offset in buf after the read value(s).
Writer functions take [buf value-or-values start ctx] and return end where end is the offset in buf after the written value(s).
broadcast
(broadcast ip netmask)
Return last/broadcast IPv4 addr based on ip and netmask
first-ip
(first-ip ip netmask)
Return first IPv4 addr based on ip and netmask
int->ip
(int->ip num)
Convert IPv4 uint32 value to IPv4 string
int->mac
(int->mac num)
Convert MAC int value to IPv4 string
ip->int
(ip->int ip)
Convert IPv4 string to uint32 value
ip->octet
(ip->octet ip)
Convert IPv4 string to bytes/octets
ip-seq
(ip-seq start end)
Return a sequence of IPv4 addresses between start and end
mac->int
(mac->int ip)
Convert MAC string to int value
mac->octet
(mac->octet mac)
Convert MAC addr string to bytes/octets
mask-int->prefix
(mask-int->prefix mask-int)
Convert network mask as uint32 IPv4 value to CIDR prefix value
