Plan 9, by default, uses - V6 format IP addresses. Since V4 addresses fit into the V6 space, - all IP addresses can be represented. IP addresses are stored as - a string of 16 <tt><font size=+1>unsigned chars</font></tt>, Ethernet addresses as 6 - <tt><font size=+1>unsigned chars</font></tt>. Either V4 or V6 string representation can be used - for IP addresses. For V4 addresses, the representation can be - (up to) 4 decimal integers from 0 to 255 separated by periods. - For V6 addresses, the representation is (up to) 8 hex integers - from 0x0 to 0xFFFF separated by colons. Strings of 0 - integers can be elided using two colons. For example, <tt><font size=+1>FFFF::1111</font></tt> - is equivalent to <tt><font size=+1>FFFF:0:0:0:0:0:0:1111</font></tt>. The string representation - for IP masks is a superset of the address representation. It includes - slash notation that indicates the number of leading 1 bits in - the mask. Thus, a V4 class C mask can be - represented as <tt><font size=+1>FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FFFF:FF00</font></tt>, <tt><font size=+1>255.255.255.0</font></tt>, - or <tt><font size=+1>/120.</font></tt> The string representation of Ethernet addresses is exactly - 12 hexadecimal digits. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Eipfmt</i> is a <a href="../man3/print.html"><i>print</i>(3)</a> formatter for Ethernet (verb <tt><font size=+1>E</font></tt>) addresses, - IP V6 (verb <tt><font size=+1>I</font></tt>) addresses, IP V4 (verb <tt><font size=+1>V</font></tt>) addresses, and IP V6 - (verb <tt><font size=+1>M</font></tt>) masks. - <table border=0 cellpadding=0 cellspacing=0><tr height=5><td></table> - - <i>Parseip</i> converts a string pointed to by <i>str</i> to a 16-byte IP address - starting at <i>ipaddr</i>.
